Concrete superficial hardener and construction method thereof

Abstract

The invention discloses a concrete surface hardener and a construction method thereof, wherein, the concrete surface hardener comprises the compositions by weight percent of 10-40 percent of inorganic silicate, 1-10 percent of alkali, 0.1-5 percent of catalyst, 0.1-2 percent of wetting dispersant, 1-5 percent of stabilizer and rest of water. The hardener prepared by the invention is characterized by easily-obtained material, simple production and convenient construction, unhealthy and environmentally harmful VOC avoidance, etc. In addition, the hardener can penetrate into the interior of the concrete to seal the capillary of the concrete, thus improving the surface density of the concrete, strengthening the impervious capability and strength of the concrete and prolonging the service life of the concrete. As the hardener does not comprise unhealthy and environmentally harmful substances, the increasingly improved requirements of the present environmental protection can be met, thus having extensive application prospect.

Description

technical field

[0001] The invention relates to a concrete structure surface treatment material, which is used for hardening and compacting the concrete surface. technical background

[0002] Concrete is the foundation of modern society. It is directly or indirectly in contact with concrete in almost every aspect of daily production and life. It is widely used in various civil and architectural structures, such as various buildings, roads, bridges, dams and flood control. Embankments, piers, etc., human activities have been inseparable from the use of concrete. Concrete consists of coarse granular aggregates and cement hydrates. During concrete construction, the components of cement undergo a very complex chemical reaction with water to form hard hydrates, which bind the aggregates filled in it together to form a structure with high compressive strength. Concrete has the advantages of economy, durability, fire resistance, high compression resistance, etc., and is widely us...
