In order to solve the partly difficulties of the current application of lightweight aggregate concrete and promote the practical application of air-entrained lightweight aggregate concrete in the field of civil engineering,the absolute volume method was used to obtain the preliminary mix proportion.

Strength reduction of air-entrained concrete under biaxiai tension-compression after freeze-thaw cycles and its failure criterion;

3-dimensional reconstruction of size distribution of air voids in air-entrained concrete;

Effect of polyacrylonitrile fiber on frost resistance of air-entrained concrete;

Experimental study on multiaxial characteristic of air-entraining concrete after freeze-thaw cycling is just in the initial stages.

Freezing thawing durability of both ordinarily and air entrained concrete exposed to Xinjiang, Qinghai, Inner Mongolia and Xizang salt lakes were determined by the accelerated freezing thawing method.

The air entrained concrete has the advantage of high impermeability and frost re sistance.

With the improvement of the requirement on highway service capabilities and its level, the slip-form construction technique is developing rapidly, at the same time, the requirement on concrete materials increases continually and the air entrained concrete as a cement concrete of good performance is widely applied.
