The Damage Model of Concrete under Coupling Action of Calcium Leaching and Load
For calcium leaching and loaded concrete in engineering structures, defining the initial damage state as basic state, the damage model of calcium leaching and loaded concrete is established using damage mechanical theory and principle of strain equality. It is shown that the mechanical properties of calcium leaching and loaded concrete are determined by calcium leaching, load and coupling effect. For calcium leaching and loaded concrete, the influence factors to stress at any point are elastic modulus, maximum strain, strain at this point and the degree of calcium leaching.
