Rice husk ash as a new type of green environmental protection and energy saving materials,has a wide development prospect in building materials. In this paper,the low temperature rice husk ash is added in the cement mortar,and compared with the blank group,the basic properties of the low temperature rice husk ash cement mortar has carried on with the systematic research. Test results show that adding rice husk ash cement mortar specimens compared with blank group,water absorption,water retention and consistency increased,and the compressive strength reduced. With the increase of rice husk ash ...
