    Abstract:A new type of inorganic permeable concrete waterproofing agent was prepared by adjusting and optimizing the formulation with lithium silicate solution,and its performance meets the requirement of JC/T 1018—2006 "Water-based permeable inorganic waterproofing agent". The effects of the modulus of lithium silicate solution,surfactant and retarder on the performance of the waterproofing agent were investigated. The change of the morphology of concrete with waterproofing agent was analyzed by SEM.
