In bittern solution, freezing thawing will not destroy all concretes, and the frost resistance of concrete is decided by the capability of concrete resisting to chemical corrosion.
在盐卤水中，混凝土一般不会发生冻融破坏，混凝土抗冻性取决于混凝土抗盐溶液化学侵蚀的性能。

The experiment also shows that after the concrete strength reach the frost-resisting critical strength, its strength and elasticity module will increase slowly with the decrease of the temperature.
试验还表明，当混凝土强度达到受冻临界强度后，随着负温值的增大其强度缓慢增长，弹性模量也有缓慢增长。

Slag brick is a new kind of hydraulic construction material. It has some evident advantages, such as large strength, strong frost-resisting, low cost and beneficial to protect environment.
