Preparation and application of sulfate-resistant concrete

Abstract

According to the preparation and application of the sulfate-resistant concrete provided by the invention, according to the technical scheme, by adding the sulfate-resistant cement, the mineral powder and the fly ash, the pressure resistance of the concrete can be effectively enhanced, so that the service life of the concrete is greatly prolonged; meanwhile, by doping sulfate-resistant cement and a salt-alkali corrosion resistant agent, the sulfate corrosion resistance of the concrete is enhanced to a certain extent, so that the compactness of the concrete is improved, the concentration of sulfate ions capable of invading into the concrete is reduced, the pore diameter of capillary pores is refined, the speed of sulfate corrosion and damage of the concrete is delayed, and the service life of the concrete is prolonged. The durability of the concrete structure is improved. And the concrete is simple in preparation aspect and clear in steps, and the working efficiency is greatly improved.

Description

technical field [0001] The application belongs to the technical field of concrete preparation, and in particular relates to the preparation and application of a sulfate-resistant concrete. Background technique [0002] Concrete, abbreviated as "concrete": refers to the general designation of engineering composite materials that cement aggregates into a whole by cementing materials. The term concrete usually refers to using cement as cementing material, and sand and stone as aggregates; Mixed with water (which may contain admixtures and admixtures) in a certain proportion, the cement concrete obtained by mixing, also known as ordinary concrete, is widely used in civil engineering. [0003] In real life, in the construction of houses and civil engineering, concrete is required as one of the raw materials for implementation. However, the existing concrete has certain shortcomings, such as the existing concrete does not have a good anti-sulfate function, and is resistant to sulp...

AI Technical Summary

Problems solved by technology

[0003] In real life, in the construction of houses and civil engineering, concrete is required as one of the raw materials for implementation. However, the existing concrete has certain shortcomings. For example, the existing concrete does not have good sulfate resistance and is resistant to The compressibility is poor, so that the service life of concrete is seriously reduced, and the preparation process is more cumbersome, and it cannot be prepared effectively and quickly, which seriously delays the construction of houses and civil engineering

[0004] The two basic properties of concrete are strength and durability. Due to insufficient awareness or attention to durability, the life of buildings is greatly shortened.
