A curing agent for sealing and hardening of concrete surface and its preparation and construction method

Abstract

The invention relates to the technical field of curing agents and particularly relates to a curing agent for sealing and hardening surface of concrete, as well as preparation and construction methods thereof. The curing agent for sealing and hardening the surface of the concrete, provided by the invention, comprises the following components in percentage by weight: 0.1-2% of fluorosilicate, 0.001-0.02% of surfactant, 5.0-30.0% of at least one of silica sol or silicate and the balance of water. The curing agent for sealing and hardening the surface of the concrete, provided by the invention, has the advantages of short curing time, thick surface hardened layer and high surface hardness, and can be widely used for surface hardening and curing treatment of concrete buildings or structures of highways, squares, garages, supermarkets, factory buildings and the like.

Description

technical field

[0001] The invention relates to the technical field of curing agents, in particular to a curing agent for sealing and hardening concrete surfaces and its preparation and construction methods. Background technique

[0002] Concrete structures, especially concrete floors, are widely used in roads, squares, garages, supermarkets, factories and other fields. After the conventional concrete surface is dried and molded, the surface will be sandy and dusty, the surface hardness is low, and voids or even micro-cracks will occur at the same time. Generally speaking, after the concrete structure is cured, the surface hardness, wear resistance and impermeability can be improved.

[0003] The Chinese invention patent application with the application number 03116794.2 discloses a surface-enhancing sealant for cement concrete, which is composed of magnesium fluorosilicate, siloxane emulsion, aluminum sulfate and water, but the surface-enhancement sealant for cement concre...
