Contribution in Study of some physical and mechanical properties of foamed concrete


Abstract in English

foamed concrete is a concrete made by cement slurry mixed with foaming agent, so that foamed concrete is lighter than conventional concrete. The objectives of this study is to produce this kind of concrete, and to study some of its physical and mechanical properties. Mix design of concrete was made for four required densities (1000, 1300,1600,1900 kg/m3), cement content of 350 kg/ m3, and water to cement ratio equal to 0.5. Different tests were performed to determine some properties of product concrete such as density, compressive strength and splitting tensile strength. The results demonstrated the possibility of production foamed concrete with wide range of density and strength. The oven dry density of foamed concrete was in the range of (870-1773 kg/m3) , compressive strength was in the range of (2.95-16.2 Mpa ), and the splitting strength was in the range of (0.32-1.76Mpa).
