THE EFFECT OF SUPERPLASTICIZERS ON CONCRETE– A REVIEW

Superplasticizers are chemicals which enhance the workability of concrete without any extra water content. They allow a higher strength concrete with lower water content. This review mainly focus on the relation between dosage of Superplasticizers and their effect on the mechanical properties of concrete. Also the fresh properties of concrete such as slump, setting time, water absorption, porosity and permeability are reviewed as they are greatly influenced by Superplasticizers. At times, Superplasticizers are actually used to enhance the fresh properties of concrete rather than strength point of view.
