What are Concrete Additives? Why do we use them? Big D

Feb 02, 2018· Types of Concrete Additives. The additives are added to a water-cement mixture to increase the life of the concrete, control setting, and hardening and fix the general concrete behavior. They can be powdered or liquid additives. The additives can be added at the manufacturing point, or at the job site.

The 23 types of Concrete Admixtures(Additives)used in Concrete

Concrete admixtures refer to the components of concrete that are added immediately before or during the mixing process, except for Portland cement, water and aggregates. Concrete admixtures can improve concrete quality, manageability, accelerate or delay setting time and other properties, and can achieve specific effects by changing these properties.
