Assessment of the Strength of Conventionally Produced Sandcrete Blocks and Burnt Bricks
(IOSR Journals, 2018-03-15) Adanikin, Ariyo; Jegele, Thompson
The fact remains that housing has been universally acknowledged as the second most important human need after food. It has been of perennial interest to the world at large since its availability touches on one of the widest spectrum of human existence. Sandcrete blocks as building materials have become so popular in many parts of Africa that although similar to bricks in many respects, they both deserve to be treated separately. It is therefore worthy of note that for an engineer to select one of these materials (block and brick), the fitness or suitability of the chosen materials for the purposed structure must be considered.Tests carried out in this research include sieve analysis, Atterberg’s limit tests (Liquid limit and plastic limit) were carried out on the materials (sand andlaterite)to be able to ascertain certain of their properties for their intended use. About ten pieces each of sandcrete block and burnt bricks were prepared for the study and density and compressive strength tests were carried out on them. Findings of the study shows the samples Liquid Limit to be 32%, Plastic Limit of 16.7%, density of the sandcrete block is 1947.47kg/m3 while the density of the burnt brick is 1823.58kg/m3 .The average compressive strength of burnt brick (5.20N/mm2 ) was found to be higher than that of sandcrete block (3.15N/mm2 ).This shows that the compressive strength is directly proportional to the crushing load on the specimens and this is shown by the regression equation y = 0.2129x+1.5;R² = 0.9817 for the burnt bricks and y = 0.14x + 0.7; R² = 0.9942 for the sandcrete blocks.The study therefore concludes that burnt bricks just like sandcrete blocks is a good construction material and can be used for sustainable building construction.

(International Journal of Research and Innovation in Applied Science, 2020-05) Adeoye, I. A.; Adeoye, I. A.; Adanikin, A. F.; Adanikin, A. F.; Adanikin, Ariyo; Adanikin, Ariyo
Globally, the world is faced with the COVID-19 pandemic which has held the economy at ransom not exempting the educational sector. This pandemic has brought about recent changes and disruptions in the educational sector which serves as a catalyst for the development of any nation. Educational sector globally is seen to be shifting towards e-learning in order to cushion the effect of this pandemic. However, developing countries evidence from the Nigeria experience are posed with the challenge of shifting from the traditional teaching method to the e-learning during the pandemic. The challenges arise as a result of the varying degree of preparedness of the institutions, lack of infrastructures, paucity of funds and policies issues in the Nigeria education sector. It is in tandem with this prevailing issues that this study examines the Nigeria educational system based on the global pandemic. This paper further discusses the necessity of e-learning; identifies and discuss challenges as well as opportunities. Recommendations to enhance e-learning during and post COVID-19 were also given
DESIGN AND DEVELOPMENT OF A WEAR TESTING MACHINE FOR MANUFACTURING LABORATORIES
(1st FUOYE INTERNATIONAL ENGINEERING CONFERENCE, 2018) Ogedengbe, Temitayo S.; YUSSOUFF, Abiodun A.; Adanikin, Ariyo
Wear of parts during manufacturing processes is inevitable but controllable. Therefore, the critical study of wear in engineering components is vital because failure of components due to wear has resulted in loss of a great deal of fortune. This study was therefore an attempt to design and fabricate a wear testing machine, evaluate the performance of the machine and compare data obtained with existing ones. Materials for the various parts were carefully selected based on desirable properties and availability. Design calculations were made for the main shaft, compression spring, belt, pulley and electric motor. The post fabrication test was carried out on the machine to evaluate the performance of the machine and results gotten reported
Evaluating the Quality Assurance and Control of Hot-Mix Asphalt from Selected Plants in South West, Nigeria
(2020-06-25) Olutaiwo, A. O.; Adanikin, Ariyo
Roads are essential necessity of every nation and it is possible that even with proper designs, the roads might not be constructed to the design standard due to poor quality assurance and control resulting in poor pavement quality. This study presents experimental results carried out on various hot - mix asphalt (HMA) samples obtained across different Asphalt plants in South West Nigeria. This was done to determine the extent to which the HMA used in the construction and rehabilitation of Nigerian roads affect their service life. Six samples of the asphalt binder (bitumen) were obtained from each plant over a period of six months and tested. The tested properties were assessed based on the level of conformance with the specifications and requirements from the FMWH General Specification (Roads and Bridges). The results revealed that HMA from plant B had a specific gravity of 1.01, penetration of 65.00 mm, softening point of 53 oC, flash point of 237.00 oC, peak Marshall Stability of 18.25 kN, flow of 3.87 mm and voids in total mixture peak value of 5.08 %. HMA from plant E had a specific gravity of 1.03, penetration of 65.00 mm, softening point of 51 oC, flash point of 239.00 oC, peak marshall stability of 18.26 kN, flow of 3.67 mm and voids in total mixture peak value of 4.99 % and these were adjudged the best in conformance with the FMWH specifications. Adequate monitoring of HMA quality for either binder or wearing courses by carrying out quality control and assurance tests is thereby recommended as it affects pavement durability and performance
Evaluation of the Structural Performance of Lateritic Soil Stabilized with Cassava Peel Ash (CPA) and Cement
(ARC journals, 2016-07-04) Olutaiwo, Adeoluwa; Adanikin, Ariyo
This study presents the result of experimental investigation on the evaluation of the effects of Cassava Peel Ash (CPA) on the index and structural properties of lateritic soil of A-7-5 (AASHTO Classification) and SP soil (USCS classification) respectively. The study was in two phases, firstly with the addition of CPA only by weight of dry soil and secondly with the addition of 5% cement with the CPA by weight of dry soil. The CPA additions were performed using 0, 2, 4, 6, 8 and 10% increment by weight of dry soil thoroughly mixed. The results of the treated soil showed that the index properties: plastic limit and the maximum dry density (MDD) decreased as the CPA addition increased whereas the liquid limit, plasticity index, Optimum Moisture Content (OMC) and California Bearing Ratio (CBR) increased as the CPA content increased. It was also discovered that the Unconfined Compressive Strength (UCS) increased up to 4% of CPA addition after which was a reduction. This implies that CPA possesses the potential for use in the modification/ stabilization of lateritic soils. Thus the use of CPA in road construction works can be said to have two major advantages – as an effective agricultural waste management and the improvement of road construction soils for better road performance.
INCESSANT POWER SUPPLY IN NIGERIA AND THE NEED FOR THE DESIGN AND PRODUCTION OF 100,000MW POWER PLANT
(International Journal of Scientific & Engineering Research, 2019-02) Oshin, Ola A.; Adanikin, Ariyo; Fakorede, Ebenezer O.; Joseph, Ojotu
The present unreliable and erratic power supply is a pointer to the fact that there is a great need for fault evaluation and reliability studies of electric power system in Nigeria. The recent blackout in the country has grounded many activities and has destroyed many industrial processes. Also, the power industries face a lot of problems. Some of the highest priority issues being generation of sufficient power, urgent clearance of faults, adequate protection and increase reliability of the system, that is, bringing a steady uninterrupted power supply to the consumers. The Nigerian power problem resulted to incessant planned, forced and unplanned outages. In addition, it has resulted to erratic and unreliable supply of electricity in the country. It has reduced productivity and has increased unemployment rate in the country to over 40million (this figure is over 70% of Nigerian youths. It has led many of the youths in the country to crime. It has led many of the deaths of many innocent people in the country. Hence, an analytical method is developed to assess the dynamic- reliability of the distribution system, as well as optimizes the occurrence of faults along each of the individual consumer point in a feeder in order to improve the performance of the system. This research publication therefore evaluates the occurrence of faults which is about 856 occurrences during a period of 8 years and outages which range between 1118 to 3785 hours per annum along the distribution lines, also the failure rates of each of the feeders were analyzed in order to improve on the supply of electricity in the distribution network. The reliability of the system which ranges between 8.57*10-12 to 9.548*10-5 were analyzed; and fault clearing techniques were carried out. Efforts were made to adequately assess the failure rates of the feeders which range between 0.003 and 0.001 and reliability of the distribution system. Efforts were also made to improve the performance of the system. As a result, it was possible to establish improvement techniques which ensure adequate and constant supply of electricity to all the consumers for industrial growth and employment: a basic solution to increasing crime rate in the country.
Investigation of the effect of alkali silica reaction (ASR) on properties of concrete pavement admixed with cow bone ash (CBA) by electrical resistivity test
(1st International Conference on Sustainable Infrastructural Development, 2019) Adanikin, Ariyo; Falade, F.; Olutaiwo, A. O.; Faleye, E. T.; Ajayi, A. J.
The use of concrete in road pavements construction in view of its durability and cost effectiveness over time have gained momentum. Cement concrete pavements however suffer deterioration due to Alkali-Silica Reaction (ASR). This study therefore investigates the use of Cow Bone Ash (CBA) in mitigating the effect of ASR using electrical resistivity test (schlumberger array probe method). The results are then compared with American Society for Testing and Materials (ASTM) standards and relevant literatures. The result of the study showed that the average resistivity at 0%, 5%, 10%, 15%, 20% and 30% CBA replacement are 298.87 Ωm, 306.23 Ωm, 215.02 Ωm, 489.31 Ωm, 382.34 Ωm and 272.53 Ωm respectively. This indicates that the peak resistivity is obtained at 15% CBA replacement which is the optimal replacement level for ASR inhibition in the concrete. The result also shows that the concrete samples are corrosion free with the least resistivity value on the 7th day at 30% CBA addition (163.03 Ωm) and the maximum value at 20% CBA addition on the 56th Day (1069.54 Ωm). The study concluded that ASR and reinforcement corrosion can be effectively controlled between 15% and 20% cement replacement by CBA in concrete/rigid pavements

(International Journal of Scientific Research Engineering & Technology (IJSRET),, 2019-06) Adanikin, Ariyo; Oyedepo, O. J.; Ajayi, J. A; Agbetanmije, K
This paper presents a comprehensive study on the use of recycled industrial and agricultural wastes converted to powder and used as fillers in asphaltic concrete production.Fillers are essential components of an asphaltic concrete as they not only fill voids in the coarse and fine aggregates but also affect the ageing characteristics of the mix.The study in evaluating the effect of different types of filler on the behavior of asphaltic concrete used broken bricks powder, broken tiles powder, cow bone ash and broken glass powder as fillers. Marshall stability and flow test were carried out on the asphaltic concrete samples. The materials used in this study include 60/70 penetration grade bitumen, river sand and crushed granites. The average marshall stability and flow values of the broken bricks powder, broken tiles powder, cow bone ash and broken glass powder is obtained as 12.21 KN, 12.51 KN, 10.75 KN and 16.05 KN for the stability and 3.10 mm, 3.06 mm, 2.69 mm and 3.28 mm for the flow respectively. This shows that broken glass powder has the highest marshall stability and flow value. The study concluded that the fillers have varying effects on the asphaltic concrete properties (rutting behavior, ageing characteristics, stripping behavior, stiffness, moisture resistance and durability) on judging from their varying marshal stability and flow values.
MECHANICAL STRENGTH DETERMINATION OF CRUSHED STONE AGGREGATE FRACTION FOR ROAD PAVEMENT CONSTRUCTION (CASE STUDY: SELECTED QUARRIES IN WESTERN NIGERIA)
(FUOYE, 2018-07-06) Adanikin, Ariyo; Olutaiwo, Adewale; Ashamo, A
In this research work, the mechanical strength of crushed stone aggregate fractions for road pavement construction in Western Nigeria was assessed. Samples of crushed stone aggregates were collected from nine (9) representative quarries spread across the states in Western Nigeria.The physical and mechanical properties of the aggregates were evaluated. The results were then compared with the specifications in international standards (BS and ASTM Standards). All the aggregate samples met the required limit for Loose Density, Water Absorption, Aggregate Crushing Value (ACV) and Aggregate Impact Value (AIV) tests. Aggregates samples from Samchase, Kopek, CCECC and SaliwaYetidipe quarries have flakiness indices exceeding the permissible limit (29.5%, 25.7%, 27.9% and 34.5% respectively). Hi-Tech and Western quarries samples have elongation indices of 44.5% and 40.3% respectively which are higher than the permissible limit. The two samples that failed Aggregate Abrasion Value test (AAV) are Hi-Tech and Western quarries, having 30.8% and 30.4% respectively. These two aggregates samples have AAV less than 35% which means they are still good for pavement construction only if the appropriate guidelines are followed (since any aggregate with AAV more than 35% is deemed weak for pavement construction). The study concluded that aggregates from Julius Berger quarry have the highest mechanical strength.
Microstructural Analysis of Concrete Using Cow Bone Ash for Alkali-Silica Reaction (ASR) Suppression
(Journal of Casting & Materials Engineering, 2020) Adanikin, Ariyo; Falade, Funsho; Olutaiwo, Adewale
Concrete pavements are prone to microstructural changes and deterioration when exposed to Alkali-Silica Reaction (ASR). ASR results in strength reduction, cracking, spalling and other defects in the concrete if left unchecked. Supplementary Cementitious Materials (SCMs) such as Cow Bone Ash (CBA) however can be used to improve concrete performance, hence its use in this study. Concrete samples were prepared at replacement levels of 0%, 5%, 10%, 15%, 20% and 30% of cement with Cow Bone Ash. The concrete samples were then subjected to petrographic and Scanning Electron Microscopy (SEM) analysis. Petrographic examination shows that the minimal and least amount of ASR gels and micro cracking were observed at 15% CBA replacement of cement in the concrete samples. Scanning Electron Microscopy (SEM) analysis shows that changes in the elemental composition of the concrete samples is related to the effect of CBA which enhances adhesion in the concrete. SEM analysis show that, in general, the change in microstructure in the concrete was mainly due to the change in the arrangement of the C-H-S compounds. The microstructure analysis indicates that CBA in concrete influences the densification of the concrete at the transition zone, resulting in a much lower porosity. This results in the concrete having a tightly bound layer that repels ingress of water and thereby inhibiting cracks and gel formation as water is a contributing factor to the ASR in concrete.
MULTINOMIAL LOGISTIC REGRESSION ANALYSIS OF VEHICULAR ACCIDENT IN NIGERIA
(FUW Trends in Science & Technology Journal, 2019-04-26) Oyedepo, Joseph; Adanikin, Ariyo; Ajagunna, Adeyinka
Vehicular accidents are major problem in developing countries and Nigeria is no exemption to this worldwide dilemma. In Nigeria, transportation has been largely by road and this means of transportation is largely inefficient and defectives resulting in vehicular accidents. The study was carried out in Akure, Ondo state Nigeria. The data used in the study were collected by collating accident records obtain from the Ondo State specialist hospital for a five-year period from the year 2013 to 2017; the records were analyzed using the multinomial logistic regression model. The findings show that 67% of the accident victims were male having death rate of 12.8%, while 46% of the accident victims are in the ages between 14 to 40 years. The findings also revealed that majority of the accidents occurred between the between the 1st and 3rd quarter of each year while the 2nd quarter generally saw a decline in road traffic accidents. The likelihood ratio test reveals that there is a significant relationship between the nature of accident, gender, and age as they have p value less than 0.05. The study recommends establishment of government policies aimed at improving health care delivery to vehicular accident victims, road network should be provided with roadway infrastructures, improvements in pavement construction and maintenance, enforcement of legislation as related to vehicle speed, pedestrian usage of roads as it is believed when all these are adhered to, vehicular accidents will reduce.
Performance Study of University of Ado Ekiti (UNAD) Transit Shuttle Buses
(Science Publishing Group, 2017-06-01) Adanikin, Ariyo; Olutaiwo, Adewale; Obafemi, Tobi
Traffic engineering uses engineering methods and techniques to achieve the safe and time efficient movement of people and goods on roadways. The safe and time efficient movement of people and goods is dependent on the transit system performance, which is directly connected to the traffic characteristics. The main parameters of performance of transport shuttles are traffic volume, speed, density and revenue; and all these are evaluated in this study. In the absence of effective planning and traffic management, current road infrastructure will not be able to cater for the future needs of the University. Students, staff and vehicle volumes have increased significantly in the last decade in the Institution, yet the performance of the transport shuttle have been dismal and unable to achieve its objectives. Findings of the study show that the morning peak period (8.00am to 9.00am) has 234 vehicles/hr, evening peak period (2.00pm to 3.00pm) has 284 vehicles/hr, while the offpeak period (11.00am to 12.00pm) has 156 vehicles/hr. The journey time from the Post Office bus stop to the University campus, measured as 34.01 minutes, was too long for the distance of 15.0km road which according to the Nigeria Highway Code should not be more than 18 minutes. The average stopping time was 6.55 minutes, average interval between arrivals of motorists was 16.40 seconds, the average queue length was 14.23 people, and the average waiting time at the bus-stop 4.17 minutes. These values were obtained using the queuing theory and shows much commuters time is lost on transit queues. The financial condition of the transit unit shows that amount generated is less than the amount expended by the transit operators. This means, in effect, that the shuttle bus operators are operating in deficit.
PUBLIC TRANSPORT POLICY IN DEVELOPING COUNTRIES: NIGERIA AS A CASE STUDY
(1st International Conference of the School of Management Technology (SMAT), 2017-03) Adanikin, Ariyo; Oyedepo, O. Joseph
This paper reviewed understudies public transport approach utilizing factors such urbanization, populace development, vehicle proprietorship, and utilization. With changes in the social, political and economic climate of Nigeria, this study looks at how these changes have affected transportation request and supply, transport arrangement and directions, and parts of economic aspects and fund identified with public transport. Conservation and enhancing of existing modes, effective utilization of people in general transport administration framework, executing appropriate transportation measures, and empowering a move towards reasonable modes were suggested. Review of government policies towards public transportation was undertaken and it shows that if developing nations like Nigeria are to achieve their economic transformation blueprint such as the Millennium Development Goals (MDGs), they require a functional, reliable and effective transport system to, among other things, connect people, places, services, opportunities and all these can only be derived by properly formulated and implemented policies with the aid of all relevant private, academic and government bodies working together.

Strength analysis of concrete pavement deformation due to Alkali Silica Reaction (ASR)
(Algerian Journal of Engineering and Technology, 2020-10-14) Adanikin, Ariyo; Funsho, Falade; Olutaiwo, Adewale
Alkali Silica Reaction (ASR) is a chemical reaction that negatively affects concrete pavements strengths and integrity. ASR impedes concrete pavements' performance due to the formation of cracks and ultimate deformation if not properly controlled. Concrete pavements are gaining more relevance due to their ability to be constructed on soils with low bearing capacity and support high traffic loadings, thus increasing the need for studies on how ASR in the concrete pavements can be mitigated. This study employed compressive and flexural strength tests to determine the strength properties and deformation of concrete pavements due to ASR when partially replaced with CBA at varying percentages. Static structural modelling of the concrete as a multiphase material in which aggregates, cracks and gel formations are considered as embedded inclusions in the cement paste is then carried out. The results are then compared with relevant standards and findings of other researchers. The study's findings reveal that all the concrete cube samples passed the recommended compressive strength for rigid pavement, which range from 35 - 40 N/mm2 at 28th day. The concrete cube samples also passed the target strength of 48.25 N/mm2 obtained from the mix design. The effect of ASR resulted in lower compressive and flexural strengths observed at 180th and 240th days with lower CBA addition, while samples containing higher CBA contents had increasing compressive strength. The static structural modelling results reveal that the maximum deformation was obtained for the concrete cubes admixed with 0% CBA with 47.045 mm while the least deformation was obtained at 30% CBA replacement with deformation value of 5.542 mm on application of a 900 KN force. Therefore, the study posits that CBA addition will help reduce Portland Cement Concrete Pavement deformation due to ASR in relation to traffic loadings.
Structural Evaluation of the Effect of Pulverized Palm Kernel Shell (PPKS) on Cement-Modified Lateritic Soil Sample
(Science Publishing Group, 2017-11-01) Adanikin, Ariyo; Olutaiwo, Adewale; Ajisafe, Segun
There have been global efforts to reduce environmental pollution of agricultural and industrial waste products by utilizing such wastes as stabilizing agents to improve soils for various uses, especially road construction. In this research, lateritic soil sample obtained from a borrow pit was tested with varying percentages of Pulverized Palm Kernel Shell (PPKS). The soil was classified as A-6 (AASHTO classification) using standard soil laboratory tests. Laboratory tests such as Atterberg Limits, Compaction, Unconfined Compressive Strength (UCS) and California Bearing Ratio (CBR) were conducted on the soil + PPKS mix only and also on soil + PPKS + 3% Ordinary Portland Cement (OPC) mix. The liquid limit (LL) and plasticity index (PI) values decreased steadily with increase in PPKS while the plastic limit (PL) value increased with up to 4% PPKS addition after which the values started decreasing. The shrinkage limit (SL) value increased with a peak value at 8% PPKS addition after which the values began to decrease. The Optimum Moisture Content (OMC) results on PPKS addition increased from 16% to 19.5% while the Maximum Dry Density (MDD) decreased by 45.18% from 1.669g/m3 to 0.915g/m3 . Addition of PPKS decreased the Unsoaked CBR by 10.79% from 68.60 to 61.20% while the Soaked CBR increased by 74.12% from 18.05% to 69.75%. UCS values for the lateritic soil and PPKS for the uncured sample, at 7 days and 14 days had peak values of 85.03, 96.46 and 100.44 respectively. From the study, it can be concluded that the properties of the Lateritic soil improved when stabilized with Cement and pulverized palm kernel shell compared to when it was stabilized with pulverized palm kernel shell alone
TREATABILITY STUDIES ON RAW WATER FROM APONMU RESERVIOR IN ILARA – MOKIN, , NIGERIA
(Proceedings of the OAU Faculty of Technology Conference 2019, 2019) Oke;, I.A.; Daramola, D.A.; Adeniji, A.A.; Fakorede, E.O.; Adanikin, Ariyo; Olabode, K.O.; Aladeyelu, A.; Arowolo, O.K.; Agada, O.V.; Agboola, A.; Gabriel, O.
Adequate water supply is an important ingredient in human’s development. In this study, samples of war water were collected from Aponmu reservoir at Elizade University, Ilara – Mokin , Ondo State, Nigeria at intervals of one week for six months. These water samples were subjected to laboratory studies (Column, pH adjustment, Jar and residual chlorine tests). Laboratory analysis of flocs formation during coagulation, iron and microbes removal of chlorination process, pH adjustment and residual chlorine after treatment of the samples were conducted using standard methods in a bench scale and executed at prototype phase. Iso-concentration curves were developed from column tests to ascertain settle-ability of the flocs during treatment. The study revealed that optimum doses of coagulant and chlorination were 80 mg/l, and 10 mg/l, respectively for effective removal of iron and residual chlorine concentration of 3 mg/l. Flocs removal was 65 % of the influent flocs in the coagulated raw water at a depth of 1.2 m and at a retention time of 60 minutes. Analysis of iso-concentration curves revealed that overall flocs removal was 89 % at 60 minutes. This indicated that for a retention period of an hour 350 mg/l of flocs would be removed from the coagulated raw water. Removal of iron from the coagulated water was between 90 and 95 % of initial iron concentration of 1.42 mg/l and removal of microbes was 99.1 % at retention time of 40 minutes. It was concluded that Aponmu reservoir can be used as water source with little modification of the current facilities, but further studies are required to ascertain effects of other factors (quality of raw water, rainfall intensity, time of concentration, discharge rate) on quality of water production.
Volumetric Properties of Cow Bone Ash (CBA) Filler-Based Asphaltic Concrete Using Aggregates from Different Sources
(Journal of Applied Research on Industrial Engineering, 2020-02-27) Adanikin, Ariyo; Funsho, Falade; Adewale, Olutaiwo
Road infrastructure in Nigeria is in a state of decay arising from various factors such as construction with low quality materials and poor maintenance. Therefore, there is the need to ensure that the materials used for construction are of the required standards and the alternative construction materials are available to reduce construction cost. In this research work, Cow Bone Ash (CBA) was used as filler in producing the asphaltic concrete samples. Marshall stability and flow test were then carried out on the asphaltic concrete samples. The materials used in this study include 60/70 penetration grade bitumen, river sand and crushed granites obtained from three selected quarries with various tests carried out to determine their suitability for use. The lower quality aggregates, based on the tests carried out on the aggregate samples, have shown to negatively affect the asphaltic concrete. The aggregate samples had average elongation index of 33.9% and abrasion index of 29.6%, while the asphaltic concrete samples had Marshall stability values (with and without) CBA of 36.99 KN and 46.84 KN, respectively. The results of the flow test on the asphaltic concrete samples gave 8.29 mm with CBA and 14.71 mm without CBA. The study also reveals that asphaltic concrete samples produced without CBA as fillers are better as they have an average stability value of 15.61 KN and average flow value of 4.90 mm than those produced with CBA which have average stability value of 12.36 KN and an average flow value of 4.90 mm. Statistical analysis shows that the source of aggregate, significantly affects properties of asphaltic concret
