摘　　要：采用硅酸锂溶液,通过调整和优化配方,制备了一种新型无机渗透型混凝土防水剂,其性能符合JC/T 1018—2006《水性渗透型无机防水剂》的要求。考察了硅酸锂溶液模数、表面活性剂、缓凝剂等对防水剂性能的影响,并利用SEM分析了涂刷防水剂后混凝土形貌的变化。A new type of inorganic permeable concrete waterproofing agent was prepared by adjusting and optimizing the for-mulation with lithium silicate solution,and its performance meets the requirement of JC/T 1018—2006 ＆quot;Water-based permeable inor-ganic waterproofing agent＆quot;. 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.
