摘　　要：介绍了电化学精制泵房地坪由于碱液结晶腐蚀导致泵基础、排水沟瓷片脱落 ,地坪不同程度隆起 ,泵进出口管线倾斜 ,严重威胁安全生产。通过采用氯丁胶乳改性混凝土及环氧砂浆面层进行更新改造 ,投用两年多 ,至今没有任何损坏。The caustic liquid crystallization corrosion of the electro-chemical pump house floor led to the spalling of the ceramic tiles of the pump foundation and drainage trench, swelling of the floor and slanting of the pump discharge pipelines, which greatly threatened the operation of the process unit. After the replacement with modified concrete of chloroprene latex and epoxy cement mortar, no damages have been found after two years of operation.
