Dry powder polymer cement waterproof mortar
The invention relates to a concrete anti-crack siliceous waterproofing agent, belonging to the technical field of concrete admixtures. The invention is characterized in that the concrete anti-crack siliceous waterproofing agent is formed by uniformly mixing the following components in parts by weight: 75-85 parts of activated modified zeolite powder, 1-3 parts of defoaming agent and 13-19 parts of high-aluminum clinker. The activated modified zeolite powder is prepared by carrying out surface modification treatment on 77-85 parts by weight of roasted composite zeolite powder by a heating process by using a composite modifier composed of 0.1-0.5 part of silane coupling agent, 2-6 parts of stearic acid, 1.5-5 parts of acetone and 2-6 parts of emulsified silicone oil. The roasted composite zeolite powder is formed by 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 milling. By using the zeolite powder as the main raw material, the concrete anti-crack siliceous waterproofing agent can overcome the defects in the existing waterproofing agent, and is capable of reducing the concrete shrinkage and enhancing the waterproof impervious function and strength of the concrete.
