Superplasticizers are nowadays commonly used in concrete technology to improve the workability of cementitious systems.
Superplasticizers, such as Poly Carboxylate Ethers (PCE), have become popular because of there superior water-reducing ability and fluidity retention ability.
They allow to reach very high mechanical performances for very demanding concrete.
How does it work?
Superplasticizers are adsorbed on the cement particles
Superplasticizers act as dispersants by electrostatic and/or steric repulsion effects
