Selection of concrete admixture types

Almost all kinds of concrete can be mixed with admixtures, and appropriate admixtures must be selected according to the characteristics of the project. The effective effect of admixture mainly depends on the type of cement, the type and performance of admixtures, the performance of coarse and fine aggregates and the impurities they contain, the mix ratio of concrete and the mixing form and mixing time of the concrete mixture. Various factors such as concrete temperature and environmental conditions.

There are many cement manufacturers in my country, and the production processes, cement varieties, and sources of raw materials vary widely; the sources of sand and gravel materials are complex and the quality fluctuates greatly; the varieties of admixtures are diverse and the quality is unstable, all of which have a negative impact on concrete admixtures. The use and quality control of concrete cause great difficulties. In the above cases, in addition to selecting appropriate raw materials and mix ratios, the correct selection of admixtures has great benefits for the production and quality control of concrete.
