用电极法测定混凝土水分冻结量的方法桂修等众所周知，砼的冻害是由于砼中水分的冻结而体积膨胀所造成的，就其机理而言，人们普遍承认由Ｔ、Ｃ、Ｐｏｗｅｒｓ和镰田等创立的静水压理论。但是目前还处于检中的水分冻结行为和冻害之间的关系尚不明确的状况，其根本原因在于... Method of determining the moisture content of concrete by electrode method It is well-known that the freeze damage of earthworms is caused by the freezing and volume expansion of the water in the earthworm. In terms of the mechanism, it is generally acknowledged by T, C, Powers and Putian. He founded the hydrostatic pressure theory. However, the relationship between frozen freezing behavior and freezing damage is still not clear. The basic reason is that...
