Abstract

The invention relates to the technical field of engineering building materials, and is mainly used for concrete leakage water as a plugging material, or for slow leakage control of concrete or mortar. This permeable crystalline plugging material is made of early-strength Portland cement, inorganic catalyst, tackifier, active core masterbatch and quartz powder. It can be used as a plugging material for concrete seepage water, or for Slow leakage treatment of concrete or mortar. The main technical indicators of this product of permeable crystalline plugging material conform to the Type II index of GB23440-2009 "Inorganic Waterproof Plugging Material". In addition, the production formula of the permeable crystalline plugging material of the present invention is simple, the source of raw materials is abundant, the preparation cost is low, and the construction is easy. The effect is good, and it can be constructed at room temperature. The parts that have been constructed with this material have the function of self-repairing the leaking water.

Description

technical field [0001] The invention relates to the technical field of engineering building materials, and is mainly used for concrete leakage water as a plugging material, or for slow leakage control of concrete or mortar. Background technique [0002] Inorganic waterproof plugging material (GB / T 23440) is a cement-based fast plugging material commonly used in waterproof plugging projects. This type of material is mainly based on cement-based materials. Compared with organic waterproof plugging materials, it has no Toxic and odorless, safe and environmentally friendly, can be carried out with water, easy construction, rapid hardening and low cost, etc., making it widely used in waterproof and anti-seepage, emergency plugging projects. [0003] In order to solve the above problems, a variety of waterproof plugging materials have appeared on the market, such as application publication number CN 102863192A invention patent application discloses a waterproof plugging material w...
