Cementitious capillary crystalline waterproof material capable of quickly repairing cracks

Abstract

The invention relates to a cementitious capillary crystalline waterproof material, which comprises the following components in percentage by weight: 30 to 50 percent of cement, 5 to 10 percent of swelling agent, 8 to 20 percent of quartz sand, 5 to 12 percent of mineral additive, 20 to 35 percent of water reducer, 0.2 to 1.0 percent of retarder, 1 to 15 percent of crystal precipitator, 1 to 12 percent of complexing agent, 1 to 13 percent of calcium ion compensating agent and 0.1 to 1.0 percent of crystal growth promoter. The cementitious capillary crystalline waterproof material has double waterproof property, high cementitious capillary crystallization capacity, capacity of quickly repairing the cracks, and excellent chemical corrosion resistance.

Description

Technical field: [0001] The invention relates to a waterproof material for construction, in particular to a cement-based permeable crystalline waterproof material with the characteristic of quickly repairing cracks. Background technique: [0002] In the contemporary era of rapid economic and technological development, industrial buildings and civil buildings have spread all over the world. Large-scale civil construction is in the ascendant. New building materials emerge in an endless stream. Advanced building technology and design are constantly being applied, making modern buildings not only beautiful and gorgeous, but also And more practical and durable. However, like everything, modern architecture is not perfect, how to prevent water leakage in building structures is still a big problem that has plagued building builders for a long time. In the field of building waterproofing, waterproof materials can generally be divided into flexible and rigid waterproof materials. Al...

Problems solved by technology

For example, the patent CN100347249C relates to a preparation method of permeable crystalline waterproof material. In this method, silane-based hydrophobic products and bentonite are mixed and dried, and then obtained by grinding and other processes. In actual production, the process is too complicated , lack of maneuverability

However, the permeable crystalline materials involved in other patents are not ideal in terms of secondary anti-permeability and crack repair capabilities.
