Abstract

The cement-based materials have significant thermal properties which play a potential role in heat dissipation into the buildings. To improve thermal properties, particularly thermal conductivity, advanced materials such as phase change materials, vacuum insulation panels, and highly porous materials are employed. In this study, a biochar mixture was introduced in cementitious materials for thermal property enhancement. The biochar was prepared from the mixture of 10 wt% rice husk and 90 wt% sawdust in the absence of oxygen with the aid of muffle furnace at a temperature of 550 ℃ for 2 hours at a rate of 10 ℃/min. The biochar dosages such as 3 wt%, 5 wt%, and 10 wt% were added with the replacement of cement in a cement paste. After 7 and 28 d, porosity, flexural strength, compressive strength, density, water absorption, and thermal conductivity were determined. The mechanical properties of samples were increased with 3 wt% biochar replacement with the cement and then decreased with 5 wt% and 10 wt%. The thermal conductivity of samples was decreased by 19–26.4% and 20.16–8.5% at 7 and 28 d respectively. The substitution of 3 wt% of biochar performed well in comparison to the control sample. Reduction of thermal conductivity of biochar-incorporated cementitious materials may be beneficial in situations where heat resistance is required due to its porous nature.
