Although concrete admixtures and their application technology are developing rapidly and becoming increasingly mature in our country, compared with advanced countries, we have to admit the fact that in many aspects, the concrete admixture industry is still in a relatively urgent stage of development and needs. stage of further improvement. Our country has a wide variety of admixture product brands, with mixed performance and unstable quality. The names of admixtures are not standardized, the technical formulas of admixtures are backward, new varieties that do not live up to their names are constantly emerging, and the quality of some employees is low. In addition, there are many varieties of cement in our country, and blending Material grades vary greatly, concrete project characteristics are different, projects are located in different regions, construction environments are different, and the concrete raw materials selected for different projects vary widely. Concrete engineering technicians are faced with such a situation of infinite variables and face too many complexities that are difficult to determine. factors, they often cannot cope with them freely. Therefore, it is particularly important to strengthen the technical training of admixture production, technical services and application personnel, and it is also a responsible move for the quality of concrete projects.
