一、破坏机理混凝土的抗冻性是混凝土受到的物理作用(干湿变化、温度变化、冻融变化等)的一方面,是反映混凝土耐久性的重要指标之一。对混凝土的抗冻性不能单纯理解为抵抗冻融的性质,不仅在严寒地区混凝土建筑物有抗冻的要求,温热地区混凝土建筑
First, the failure mechanism Frost resistance of concrete is the physical role of concrete (wet and dry changes, temperature changes, freezing and thawing changes, etc.) on the one hand, is one of the important indicators of the durability of concrete. Frost resistance of concrete can not be simply understood as the nature of resistance to freeze-thaw, not only in frosty concrete structures have antifreeze requirements, warm concrete buildings
