Concrete sealing curing agent and construction process thereof

Abstract

The invention provides a concrete sealing curing agent. The concrete sealing curing agent is composed of 50-70 wt% of active silicate, 10-20 wt% of a mixture of magnesium fluosilicate and zinc fluosilicate, 1-3 wt% of hydrofluoric acid, 1-3 wt% of a polyguanidine salt, 1-3 wt% of a micro-expanding agent, and the balance of water and other assistants. The concrete permeation sealing curing agent isa colorless, odorless, non-toxic and harmless novel antibacterial building material, a polymerization solution using active silicate as a main component can be applied to renovation of a newly-pouredconcrete ground or an old ground, by sufficient permeation, the effective components can quickly undergo a chemical reaction with free calcium in the concrete so that crystal colloid is generated tofill structure gaps, the compactness of the structure is improved, a sealing entity as hard as rock is formed on the surface layer of the concrete, the strength and the wear resistance of the surfacelayer of the concrete structure are greatly improved, the ground is permanently dustproof, anti-skid, wear-resistant, hard, pressure-resistant, impermeable, weather-resistant, chemical-resistant, bright, environment-friendly and the like, and the service life of the ground is prolonged.

Description

technical field [0001] The invention relates to the technical field of cement floor improvement coatings, in particular to a concrete sealing and curing agent and a construction process thereof. Background technique [0002] Concrete, referred to as concrete, refers to the general designation of engineering composite materials that aggregate aggregates into a whole by cementitious materials. The term concrete usually refers to cement as cementitious material, sand and stone as aggregates; (may contain admixtures and admixtures) according to a certain proportion, the cement concrete obtained by stirring, also known as ordinary concrete, has the advantages of economy, durability, fire resistance, high compression resistance, etc., and it is widely used in civil engineering. [0003] During the hardening process of concrete, the surface layer and the internal structure contain a large number of interpenetrating pores. As a result, during the service process of concrete structur...

Problems solved by technology

At present, the inorganic concrete floor hardeners on the market are mainly composed of three types of products: the first type is a sodium-based salt product mainly composed of sodium silicate, which can give priority to improving the strength and wear resistance of concrete, but has poor durability and is easy to Pan-alkali affects the floor effect in the later stage; the second type is potassium-based salt products with potassium silicate as the main component, and its performance is not significantly improved compared with sodium-based salt; the third type is lithium-based salt products with lithium silicate as the main component. Base salt products, most of the products imported from abroad are such products, and their sealing and hardening effects are more significant, but because they are imported products, their prices are relatively expensive
