| Abstract: | Magnesium oxide,magnesium sulfate and coal ash are used as the main materials. Besides,they are also mixed with composite additive of polypropylene fiber to produce magnesium-based foam concrete. The experiment studies the thermal conductivity,compressive strength,elasticity modulus,shear strength and splitting tensile strength of magnesium-based foam concrete. For magnesium-based foam concrete of different sizes and the same dry density,FEMAP simulation technology is utilized to compare stress-strain curve and the impacts of size effect on compressive strength. |
