Abstract

The invention belongs to the technical field of concrete, and relates to a concrete curing agent. The concrete curing agent comprises the following raw materials: potassium silicate, a penetrating agent, a water repellent, a surfactant, a surface modifier, a reinforcing additive and deionized water. The method is simple in process and reasonable in step matching; industrial popularization and application are facilitated; and the prepared concrete curing agent can obviously improve the use quality of concrete and prolong the service life of the concrete.

Description

technical field [0001] The invention belongs to the technical field of concrete, and more specifically relates to a concrete curing agent and a preparation method thereof. Background technique [0002] During the hardening process of concrete, its surface and internal structure contain a large number of interpenetrating capillary pores, resulting in the phenomenon of sand and ash during the use of concrete, resulting in accelerated deterioration of the concrete structure and reducing the service life of the concrete. [0003] At present, the domestic concrete curing agent is mixed with water, penetrates into the concrete and reacts with calcium and magnesium ions in the concrete, and forms a gel in the pores of the concrete to improve the strength and wear resistance of the concrete. However, the formed gel substance will decompose again when it encounters water for the second time, and will lose its hardness and luster. This is why the ground is damaged and dull after sever...
