In this paper, the frost resistance on different water-cement ratio of concrete after the air-entraining agent admixture. When the gas is controlled about 4%, with the lower water-cement ratio, freeze-thaw resistance of concrete is increased significantly. And then the frost resistance of YC20 and YC40 concrete which are mixed in efficient air-entraining water-reducing agent were studied, the experiment results that when the concrete YC40 reached F300, gas content reached more than 4.5%,and the strength without reducing, the durability would improve. But the YC20 is different, so, GL-B4-efficiency air-entraining water-reducing agent does not apply to the water-cement ratio above 0.6 of the concrete
