Product features: Spraying concrete curing agent is a kind of polymer material. After spraying on the concrete surface, it solidifies to form a dense film, which insulates the concrete surface from the air and greatly reduces the evaporation loss of water on the concrete surface. Therefore, the hydration can be completed to the maximum extent by using the moisture in concrete to achieve the goal. The spraying amount depends on the product and the effect to be achieved, and should be determined according to the product description or test.
When the curing agent is sprayed on the concrete surface, it can not only form a covering film on the concrete surface quickly, but also react with the free calcium hydroxide in the shallow layer of concrete to form a dense and hard surface layer in the permeable layer, so as to prevent the water in the cement concrete from evaporating, make the cement fully hydrated and achieve the purpose of autotrophic. The purpose of curing agent is to protect concrete, because the surface of concrete loses water during the hardening process, and the concrete will shrink and lead to cracks, which are called plastic shrinkage cracks. Before the final setting of concrete, it is impossible to spray water for curing, so using curing agent is a better choice. Some concrete structures are difficult to be wetted by water, and can also be protected by curing agent. Concrete curing is surface moisturizing, and the essential function of curing agent is "protection", not "curing", because the concept of curing is to prevent concrete from losing water, replenish water, help cement hydrate and make its strength grow healthily.
Product performance:
1. Compared with the concrete covered with wet sacks, the 28-day strength retention rate of concrete using this curing agent is over 98%.
2. It has no adverse effect on the drying shrinkage of concrete.
3. The concrete surface cured by this curing agent does not affect the decoration.
4. Non-toxic, tasteless and harmless to human body.
How to use:
1. The elevation and slope are divided into two parts. For the first time, spray or smear it evenly in the area with the dose of 65438+6/00. After about 40~60 minutes, the surface appears transparent or translucent, that is, it is sprayed again, and the dosage is 65438+4/00.
2. The horizontal plane should be completed at one time. If it is uneven, it is best to complete it in two times. Avoid sprinkling water or getting wet in the rain within 4 hours after maintenance. If you spray water or get wet within 2 hours, you should re-maintain, and the maintenance will be halved within 2~4 hours. If it takes more than 4 hours, there will be no such scruples.
Precautions: The curing agent of concrete is multi-agent emulsification such as oil wax and resin. If secondary construction is needed, the joint surface, wall surface and steel bar should be isolated when spraying, and the plane secondary construction can be carried out only after the surface is planed with a planer. In case of the above situation, please buy pure resin curing agent from our company.
The above is what Bian Xiao, Tuba Rabbit, introduced to you about the use and precautions of concrete curing agent. I believe everyone has a deeper understanding of concrete curing agent. Every part of the project is essential. Without any tools, no raw materials can be used. Just like concrete curing agent, it sounds useless, but after Bian Xiao's introduction, everyone should understand its importance. Without concrete curing agent, concrete may not be able to complete the hydration reaction well, so everyone should study the correct use of concrete curing agent!
