Cementitious capillary crystalline waterproofing material

Abstract

The invention provides a capillary crystalline waterproofing material which comprises silicate cement, quartz sand, a crystal master batch, latex powder, other active materials, and the like, whereinthe ratio of aggregate cement to the quartz sand is 1:1.89; the crystal master batch is dehydrated gypsum or calcium chloride, and the like; and the proportion of the crystal master batch is between 3percent and 7 percent. The waterproofing material has the bonding force, the surface adhesive force, quantities of formed crystals, the strength and the anti-penetration force of concrete and can ensure that concrete structures cannot be damaged. The capillary crystalline waterproofing material has wide range of application, is applied to projects of basements, civil air defenses, tunnels, ports,wharfs, swimming pools, dams, irrigation ditches, and the like, solves the problems of concrete projects, achieves the purpose of permanent water proofing and also protects concrete and reinforcing steel bars from corrosion.

Description

technical field [0001] The invention relates to a waterproof material, especially a permeable crystalline waterproof material. Background technique [0002] Waterproofing of buildings and structures has always been a major problem that plagues the quality of the project and its use. PVC, SBS membranes, and modified asphalt membranes are commonly used at present, and their service life is relatively low for waterproofing. Generally, they are used for 5-10 years. Aging easily. Cement-based permeable crystalline waterproof materials are based on ordinary silicate materials and powder materials mixed with a variety of special active chemical substances. Using the inherent chemical characteristics and porosity of concrete itself, under the reverse guidance of water, with the help of strong The permeation function of the micropores and capillaries in the concrete reverses with water, filling, catalyzing the micropores, capillaries and microcracks in the concrete, and combining wi...

Problems solved by technology

[0003] At present, there are well-known brands such as Canada's XYPEX (Saipass), France's DIPSEC, America's PENETRON (expansion internal transmission), Australia's DR1BOND and other well-known brands in foreign markets. China has introduced and sold foreign products since the late 1990s, but the price is expensive.
