Polycarboxylate Superplasticizer (PCE) Powder
Advanced dry powdered high-range water reducer for modern concrete admixture systems.
Polycarboxylate Superplasticizer (PCE) Powder is a high-range water reducer based on modified polyether chemistry for low water-cement ratio concrete, slump retention and high-performance cementitious systems.
This grade provides strong water reduction, practical slump control and broad compatibility in modern concrete formulations when used with validated mix design.
It is suitable for ready-mix, pumped concrete, precast production and dry-blended admixture systems that need stronger dispersion than conventional lignosulfonate-based water reducers.
Key Performance Functions
High-Range Water Reduction
Supports low water-cement ratio concrete and higher strength design.
Slump Control
Helps improve slump retention during transport and placement.
Flexible Dosing
Can be formulated for modern cementitious systems after dosage validation.
Air Management
Supports control of unwanted entrapped air when properly formulated.
Non-Corrosive Formula
Free of calcium chloride, nitrates and other corrosive materials.
