Concrete crack resistance silicon waterproof agent
The invention discloses a concrete crack resistance silicon waterproof agent, and belongs to the technical field of concrete additives. The waterproof agent is prepared by uniformly mixing 75-85 parts by weight of activated modified zeolite powder, 1-3 parts by weight of an antifoaming agent and 13-19 parts by weight of high-aluminum clinker; the activated modified zeolite powder is obtained through carrying out surface modification treatment on 77-85 parts of roasted composite zeolite powder by using a composite modifier composed of 0.1-0.5 parts by weight of a silane coupling agent, 2-6 parts by weight of stearic acid, 1.5-5 parts of acetone and 2-6 parts of emulsified silicone oil via a heating process; and the roasted composite zeolite powder is prepared through the following steps: mixing 50-70 parts of zeolite powder, 2-6 parts of Al2(SO4)3 and 6-10 parts of CaSO4, roasting and grinding. The zeolite powder is adopted as a main raw material in the invention, so the waterproof agent can overcome the disadvantages of present waterproof agents, reduces the shrinkage of concrete, and enhances the waterproof and impervious functions of the concrete and the strength of the concrete.
