Abstract:The effects of pore and pore water on the overall initial mechanics properties of concrete in moist condition are investigated by employing the theory of micromechanics. Concrete is a porous material with two pore types, active pore and entrained non-active pore, and the former will be filled with water in moist environment. The non-active pore and the pore water in active pore are considered as two types of inhomogeneous inclusion. Based on the effective inclusion theory and the Mori-Tanaka's concept of average field, a double inclusions model is proposed. The influences of further hydration and water viscosity in pore on the mechanics property of concrete in different saturated degrees are considered in this model. The theoretic results compare well with the previous test data and illustrate that it can be used to predict the initial elastic modulus of moist concrete.
