混凝土盐冻损伤机理
Salt-Freezing Damage Mechanism of ConcreteThe study investigates the deterioration of concrete subjected to cyclic freezing in a saline environment. It identifies the formation of glauberite (Na2SO4·10H2O) as a primary damage mechanism, where the crystallization pressure and pore expansion lead to microcracking and strength loss. / 本研究调查了混凝土在盐冻循环环境下的劣化过程。研究确定石膏（Na2SO4·10H2O）的形成是主要损伤机理，其结晶压力和孔隙膨胀导致微裂纹产生和强度损失。
