Guide on Admixtures in Concrete: 10 Types and their Uses
a) Plasticizers. Prior to concrete being put to use, it has to obtain a certain consistency. Plasticizers are chemical admixtures that decrease the water-cement ratio in concrete by around 5% to 12% and obtain the required consistency. Their addition to the mix increases the workability of the concrete and makes it easier to pour and place in accessible locations.
