With the development of science and economy, in the construction and road engineering, new performance requirements of concrete are constantly put forward. Practice and experience show that the use of concrete admixtures to meet these requirements is a very effective means. At present, it has become an indispensable fifth component in concrete. It is not only regarded as a powerful measure to improve concrete strength and concrete performance, but also shows that it has a very significant effect on saving cement and saving energy. Domestic In all efforts to promote the use of various types of concrete admixtures.
