Cement-based permeable-crystallization waterproof material

Abstract

The invention relates to a cement-based permeable-crystallization waterproof material and belongs to the technical field of building materials. The waterproof material is characterized by being prepared from the following ingredients in weight proportion: 56 to 62 parts of cement, 27 to 33 parts of quartz sand, 7 to 11 parts of complex catalyst and 1 to 3 parts of zeolite waterproof agent. The complex catalyst is prepared from the following ingredients in weight proportion: 87 to 75 parts of zeolite powder, 5 to 10 parts of lithium silicate, 5 to 10 parts of gluconate and 3 to 5 parts of isobutyl triethoxy silicane, wherein the ingredients are mixed and modified. According to the cement-based permeable-crystallization waterproof material, only the four ingredients of the cement, the quartz sand, the complex catalyst and the zeolite waterproof agent are utilized, and prices of the four ingredients are all limited; thus, manufacturing cost is low, and the cement-based permeable-crystallization waterproof material is easy to popularize; in addition, waterproof performance is remarkably improved; ingredient constitution and application of the cement-based permeable-crystallization waterproof material can both meet related requirements for national green environment-friendly building material products.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a cement-based permeable crystalline waterproof material. Background technique [0002] With the extensive use of concrete in building construction, the lack of durability of concrete structures has attracted more and more attention. Among them, the infiltration of water is an important reason for the deterioration of concrete and the reduction of its durability. Therefore, it is necessary to waterproof the concrete. To avoid deterioration of concrete and improve its durability. "Cementitious Capillary Crystalline Waterproofing Materials" is referred to as CCCW (Cementitious Capillary Crystalline Waterproofing Materials). As a new type of rigid waterproof material, it can better solve the problem of concrete water seepage. It entered my country in the form of SMD core masterbatch in the 1980s. market, because of its high price, it is not easy to promote in ...
