Description
Standard quality building material is the demand of this present age. It is a good attempt to draw
some ideas about the use of composites in modern building materials. This study experimentally
investigates the effect of varying oil beanstalk (OBS) filler and Portland cement (Cmt) additives
on thermo-mechanical properties of aluminium dross (Aldr)-Portland cement oil bean-reinforced
composites. The specific heat capacity, thermal conductivity, thermal resistivity, thermal
diffusivity, thermal effusivity, and compressive strength were determined at a different variation
of filler content to investigate its effects on the developed composites' behaviour building
ceilings application. Result shows that the physical and mechanical properties of
triad 0.6Aldr0.3Cmt0.05G0.05OBS, 0.6Aldr0.32Cmt0.05G0.03OBS composites are better
than 0.6Aldr0.34Cmt0.05G0.01OBS composites. Developed samples with Portland cement binders were
observed not supporting combustion in the combustion calorimeter, confirming their flameretardant
characteristics. Thermal analysis indicates that reduced additive results in poor thermal
performance despite an increment in Portland cement content. The least thermal conductivity
value (0.0195 W/m2K) was obtained for sample 2 produced with 60% aluminium dross, 32%
Portland cement and 3% oil bean stalk. The developed ceiling materials specific heat capacities
increased by 10.33–386.83% compared to asbestos. Compared to Polyvynylchloride (PVC)
ceiling material gave a 40.81% reduction in sample 2. The calorific value of oil bean stalk obtained using the combustion calorimeter is 17.80 MJ/kg, lower compared to pulverized
coconut shells. It is observed that the best performance of the composite is achieved at moderate
Portland cement and filler ratios. A new method of curbing fire spread and providing thermal
comfort is essential in this new age of building composite, sustainable cities, and communities;
this will come to the fore when inbred exceptional thermal, combustion, and mechanical
properties are found in developed building ceilings. The percentage variation of filler on the
matrix material necessitates improvement in their behaviour in performance.
