Cement concrete maintenance agent

Abstract

The invention discloses a cement concrete maintenance agent, which comprises a curing maintenance agent and a water blocking maintenance agent, wherein the curing maintenance agent is directly sprayedor brushed on the surface of concrete to form a curing maintenance layer, and the water blocking maintenance agent is sprayed or brushed on the curing maintenance layer to form a water blocking maintenance layer. According to the present invention, the curing maintenance agent and the water blocking maintenance agent are separately used, and are not mixed, wherein the curing maintenance agent provides good filling effect on the surface of concrete to make the water blocking maintenance agent having hydrophobic property have good film forming effect so as to improve the water retention effect,the curing maintenance layer formed by the curing maintenance agent has good thermal conduction effect, the discharge of hydration heat cannot be affected by the coating of the curing maintenance agent and the maintenance, and the water blocking maintenance layer having thermal insulation effect has good light diffusion effect and good water blocking effect through glass micro-beads, glass scalesand titanium white so as to reduce the influence of light radiation heating.

Description

technical field [0001] The invention belongs to the technical field of concrete curing, and in particular relates to a cement concrete curing agent. Background technique [0002] Concrete is the most used and most important building material in modern buildings. The strength of concrete is mainly provided by the hydration and hardening of cement. The hydration and hardening of cement is a long-term process. The hydration and hardening of cement requires free water. Therefore, in order to ensure that the concrete has good hardness, it is necessary to ensure that there is sufficient water during the hardening process of the concrete. However, in actual operation, due to the influence of the temperature and humidity of the construction environment, the free water in the concrete is easy to evaporate, resulting in the failure of the concrete to reach the optimum level. Optimum hardening strength stops the hydration process and even forms cracks on the concrete surface. [0003]...

[0003] In order to make the concrete achieve a good curing effect, it is necessary to moisturize and maintain the concrete. The most primitive way is to spray water on the concrete surface during the curing process to keep the moisture. However, this process consumes a lot of water resources, and in some construction locations, maintenance The transportation of water will also consume a lot of resources. Therefore, in modern concrete buildings, concrete curing agents are often used to spray or paint on the surface of the curing concrete. Concrete curing agents are mainly divided into film-forming and non-film-forming types. The former is through Form a layer of water-blocking film on the concrete surface to reduce the free water loss rate of concrete during the hardening process, thereby improving the hydration and hardening effect of cement in concrete. Non-film-forming curing agents play a curing effect on the concrete surface through penetration. However, in the prior art, during actual construction, the bonding ability of the curing agent film and concrete on the concrete surface is relatively poor, which affects the film-forming effect, and requires the use of a large amount of curing agent to achieve the purpose of curing. In order to solve this problem, the present invention provides The following technical solutions
