Abstract: Concrete and sand that were replaced by coal bottom ash concrete were analyzed and compared for strength and heat conductivity. Thermal conductivity was measured using a Hot Disk TPS 2500S instrument, based on the Transient Plane Source technique. When the samples contained 40% replacement coal, the thermal conductivity value was reduced by 35%, for 60% replacement the thermal conductivity value was reduced by 36.5%, and for 100% replacement, thermal conductivity was reduced further to around 51%.
