This technology relates to the field of concrete, specifically a high-efficiency anti-segregation agent for concrete and its use method.
With the development of society and the acceleration of urban construction, people's requirements for commercial concrete are constantly increasing. In actual projects, especially the problem of concrete segregation seriously affects the quality of concrete and concrete construction. High-efficiency anti-segregation agents for concrete can effectively solve the problem of concrete segregation, reduce the sensitivity of concrete to the amount of water-reducing agent, and effectively improve the quality of concrete. Construction performance of mixed concrete.
The purpose of this technology is to provide a high-efficiency anti-segregation agent for concrete that can effectively solve the problem of concrete segregation and its use method, so as to solve the problems raised in the above-mentioned background technology. .
In order to achieve the above purpose, this technology provides the following technical solutions: An anti-segregation agent for concrete: using polyethylene glycol as the anti-segregation agent mixed with polycarboxylic acid Acid superplasticizer is used in concrete, and its molecular weight is 200~2000. Considering the cost and sensitivity of use: the preferred molecular weight of polyethylene glycol is 800 ~ 1000.
