Aqueous permeable concrete sealing and curing agent

Abstract

An aqueous permeable concrete sealing and curing agent is composed of the following components in percentage by weight: 75 to 95 wt% of silicate, 0.1 to 1.5 wt% of penetrating agent, 0.1 to 1.0 wt% of promoter, 0.1 to 2.5 wt% of waterproof agent, and the balance being water. The aqueous permeable concrete sealing and curing agent can be diluted by water according to the situation of concrete base material; diluted agent can be sprayed or painted on the surface of concrete structure, the active components can penetrate to a depth of 2 to 8 millimeters in concrete under the effect of promoter; the active components can react with calcium hydroxide crystals in concrete to generate calcium hydroxide hydrate gel, which can fill and enclose the pores in concrete, thus the strength and wear resistant performance of concrete pavement are largely improved, the phenomenon of ash generation and sand generation is avoided, and the anti-permeability and stain resistant properties of pavement are prominently improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a water-based permeable concrete sealing and curing agent. Background technique [0002] As a widely used building material, concrete plays a huge role in modern construction projects. However, ordinary concrete is used as a ground material during its service period due to inherent deficiencies, poor construction or chemical erosion, rolling by forklifts, etc., resulting in the loss of coarse aggregates, potholes, peeling or loosening of the entire ground. In order to avoid these phenomena, materials such as epoxy resin are usually poured on the concrete surface, which not only increases the construction cost, but also increases the later maintenance cost. [0003] In recent years, concrete curing agents have appeared on the market to improve the compactness and surface hardness of concrete structures to improve the effect of concrete floors. At present, there are tw...

Problems solved by technology

[0004] The existing concrete floor strength and wear resistance are not high, and the problems of ash and sand are common. We have developed a seal curing that can effectively improve the wear resistance of the concrete floor, avoid ash and sand, and improve its impermeability and pollution resistance. agent, has important value and significance
