Abstract

The invention provides crystalline-type waterproof paint for preventing cement leakage, which belongs to the field of waterproofing work in constructional engineering, solves the technical problem of cement leakage prevention in the prior art, and is prepared from the following raw materials in weight ratio: 52.5 ordinary Portland cement, No. 95 granulated blast furnace mineral powder, penetrating agent, expanding agent, silica fume, quartz sand, modified bentonite, modified sodium silicate, complexing agent and crystallized precipitant. The cement-base waterproof paint provided by the invention enables concrete to be waterproof, is inorganic material, has the service life as long as concrete, improves concrete density to improve the concrete strength, and has the characteristics of low possibility of leakage, carbonization resistance, resistance to harmful substance permeation, simplicity in construction operation, low construction cost and the like.

Description

technical field [0001] The invention belongs to the field of waterproof engineering in construction engineering, and relates to a crystalline waterproof coating for preventing cement leakage. Background technique [0002] The buildings we see in our society generally have waterproof and anti-seepage requirements, but the ordinary concrete used in construction projects has poor waterproof performance. There are many tiny gaps in ordinary concrete that can be seen or even invisible to the naked eye. It penetrates into the building through tiny gaps, forming a concrete structure leakage phenomenon, [0003] The main principle of waterproof coating is that concrete undergoes a secondary hydration reaction under the action of active chemical substances, forming crystals that are insoluble in water and other liquids, thereby blocking the capillary pores of concrete to achieve waterproofing, and the crystals are synchronized with the life of concrete , so it can play a permanent w...
