What is Concrete admixtures? Concrete admixtures, also known as concrete additives, is a chemical substance that is added in the process of mixing concrete, accounting for less than 5% of the cement mass, and can significantly improve the performance of concrete. The characteristics of concrete admixtures are many varieties and small dosage, which have a great influence on the performance of concrete, and have the characteristics of less investment, quick effect, and significant technical and economic benefits. With the continuous advancement of science and technology, concrete additives have been used more and more, and admixtures have become the fifth important component of concrete in addition to the four basic components. What are the types of concrete admixtures? If concrete admixtures are classified by function, there are five different classes of chemical admixtures: air-entraining admixtures, water-reducing admixtures, retarders, accelerators, and plasticizers (superplasticizers). What are concrete admixtures used for? Concrete admixtures are added to water-cement mixtures to extend the life of concrete, control setting and hardening, and fix the general properties of concrete. They can be powder or liquid additives. Concrete admixtures can be added at the point of manufacture or on the job site.
