This paper briefly introduces the organosilicon waterproofing agent at home and abroad, the research significance and the waterproof mechanism of several groups of experiments. Through the comparative analysis of silicone coated with mixing effect, cement mortar mixing silicone water in unit time was significantly lower than that of ordinary cement mortar, and with the increase of silicone content, water absorption of modified cement reduce the rate of mortar. The effects of different kinds of organosilicon on the mechanical properties of concrete are also studied. The mechanical strength of the mortar can be reduced by the machine silicon waterproof agent.
