Abstract

The invention discloses a cement-based capillary crystalline waterproof material. The active chemical substances in the cement-based capillary crystalline waterproof material have relatively strong permeability, can be deeply permeated and diffused into internal pores of cement concrete by taking water as a carrier, and chemically react with calcium ions in the concrete to generate water-insoluble silicon-calcium hydrates (branch and tendril-shaped crystals). The crystals are filled with capillary tube pores, the crystals and the concrete are integrated, capillary channels in the concrete are blocked, and therefore the concrete is compact, water leakage is prevented, and the waterproof and anti-seepage functions are achieved. The waterproof material disclosed by the invention has the characteristics and properties of multiple anti-permeability and self-repairing, and has extremely high compression resistance and bending resistance. A waterproof layer prepared from the waterproof material can form a complete system with the surface of concrete, the interface bonding force is high, separation is avoided, and permanent waterproofness can be achieved.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a cement-based permeable crystalline waterproof material. Background technique

[0002] At present, due to the improper selection of waterproof materials on the surface of buildings in a humid environment, water seepage often occurs on the surface of the building, resulting in corrosion of steel bars inside the building, peeling of the concrete pavement, and other problems, which seriously affect the durability of the building and the normal use of the building. life.

[0003] In traditional construction projects, it is generally used to lay waterproof membranes on the facing or back surface of the ordinary concrete surface to isolate the water source. However, this construction process requires special treatment of the joints of the waterproof layer, such as the use of step-reinforced construction joints. Seaming method, the process is more complicated. In order to ...
