Hashin-Hansen's equation based on the low of mixture is well known as an equation for estimating the static modulus of elasticity of the ordinary cement concrete as a two-phase composite material having the binder and particle phases. On the other hand, the porous concrete is three-phase composite material consisted of the binder, coarse aggregates and voids phases.
The equation for estimating the static modulus of elasticity of the porous concretes is proposed by applying the law of mixture introducing the correction coefficient of the voids.
