Experimental Study on Effects of Porous Material Addition on Concrete Thermal Insulation Performance
In this paper,a variety of porous materials such as ceramic particles,hemp fiber and straw fiber are selected as additives,and mineral processing dust and fly ash are added to prepare foamed concrete,and its mechanical properties and thermal insulation effects are tested under different mass fractions.The experimental results show that the addition of porous materials has a significant effect on the thermal insulation performance of foamed concrete,especially the ceramic particles can significantly reduce the thermal conductivity of concrete,and the appropriate addition of filler can significantly improve the mechanical properties of foamed concrete,in which the performance of beneficiation dust is slightly better.This study is conducted to investigate the effects of different types of porous materials on the thermal insulation performance of foamed concrete.
