PCE Superplasticizer (Polycarboxylate Ether Water Reducer)
CAS Number: 9003-01-4
Polycarboxylate ether (PCE) superplasticizer is a high-performance water-reducing admixture based on comb-shaped copolymer technology, offering water reduction rates exceeding 30%. It imparts excellent workability retention to concrete mixes without retardation and is compatible with supplementary cementitious materials. Widely adopted in ready-mix, precast, and high-performance concrete applications.
