In Japan, advanced superplasticizers that exhibit excellent slump (fluidity) retention,viscosity control and air entrainment control, as well as greater water reduction than conventional superplasticizers, have been marketed for more than 15 years.During this time, these advanced superplasticizers have become indispensable in the production of ultra high-strength and high-fluidity concretes.Admixture companies have striven to develop and improve new functional materials.Polycarboxylate-based materials have become the main raw material for advanced superplasticizers, since these possess a molecular structure that can be easily manipulated to impart new functions.In this paper, the authors outline the current status and future trend of this technology.
