摘要：

In order to increase freeze-salt scaling resistance of concrete, effect of water-binder ratio, fly ash, slag and silica fume on freeze-salt scaling resistance are researched according to the CDF method. The results show that the scaled mass and the dynamic modulus of elasticity loss rate of the concrete are reduced with decreasement of water-binder ratio. When mineral admixture compound is added into concrete the scaled mass and the dynamic modulus of elasticity loss rate are also reduced. Compared with fly ash and slag the trend is more obvious as result of fume and slag added. The scaled mass and the loss rate of dynamic elasticity modulus are slightly reduced with decreasement of fly ash and slag. But the scaled mass and the loss rate of dynamic elasticity modulus are obviously reduced with increasement of silica fume and slag.
