Abstract
The effect of 120-180 μm quartz sand on the mechanical properties, water absorption, thermal conductivity and porosity of foam concrete is studied in this paper. The results show that the addition of quartz sand can effectively enhance the compressive strength of foam concrete, but it will increase the thermal conductivity of foam concrete and reduce the thermal insulation performance of foam concrete. However, when the amount of quartz sand is 50%, foamed concrete has excellent comprehensive properties.
