Abstract
The emission of harmful elements from burning building ceiling materials and their attendant health effects on
inhabitants within the vicinity of the emitted harmful elements is increasingly becoming a source of concern globally.
Hence, the need to develop eco-friendly flame-retardant composite materials suitable for house ceiling purposes to
forestall unwanted toxic emissions. This work identified the chemical structure of developed composite products and
their emission performance during combustion. X-ray Diffraction (XRD) analysis was used for phase quantification
and E550 combustion gas analyzer for emission characterization of the developed composites. Thermolyne 950oC
oven was employed for the combustion analysis of the prepared composite at 500oC. Quasi negligible SO2 level and
CO2 exist; however, A4, 0.3Aldr0.23Cmt0.3Si0.05G0.12CS recorded maximum CO level, an indication of toxic affluence.
The low mass losses of all of the composite materials, especially for A2, 0.6Aldr0.34Cmt0.05G0.01OBSretard
significantly due to its activities by the retardant constituent. The flame retardant nature of all produced composite
was evidenced in their elemental composition, as there was an absence of flammable element and presence of stable
insulating compound providing retardance to flame occurrences. These suppressions in the flame inclination of the
reinforced materials were noticed within the boundaries of the ceiling crystals from the structural examination. The
intermetallic phase from the diffraction intensities showed the presence of a significant second bond interstitial solidphase
across the matrix, especially for 0.6Aldr0.34Cmt0.05G0.01OBS ceiling material
