Polycarboxylate ether superplasticizer (PCE) or just polycarboxylate (PC), work differently from sulfonate-based superplasticizers, giving cement dispersion by steric stabilisation, instead of electrostatic repulsion.See all results for this questionsp.info How are water reducers and superplasticizers used in concrete?Water reducers, retarders, and superplasticizers are admixtures for concrete, which are added in order to reduce the water content in a mixture or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture.See all results for this question
Water-reducing admixtures or plasticizers are all hydrophilic surfactants which, when dissolved in water, deflocculate and disperse particles of cement. By preventing the formation of conglomerates of cement particles in suspension, less water is required to produce a paste of a given consistency or concrete of particular workability.See all results for this questionsp.info What's the difference between a retarder and a water reducer?The main difference between these two is the water-reducing characteristic in Type D that gives higher compressive strengths by lowering w/cm ratio. Retarding admixtures are used to slow the rate of setting of concrete.See all results for this questionsp.info Polycarboxylate Superplasticizer - High-performance ...Polycarboxylic acid series high-performance water reducing agent is a kind of surface active agent whose molecular structure is carboxyl-containing graft copolymer.
