The frost resistance and impermeability are important indicators of the durability of cement mortar. The effect of rice husk ash on the durability of cement mortar is demonstrated by freezing and thawing test and imperme-ability test system. The experimental results show that the durability of concrete can be improved by adding rice husk ash to cement mortar. Through the test it can be seen that the addition of rice husk ash can improve the frost resistance of rice husk cement mortar, which can obviously reduce the loss rate of compressive stre...
