High-Range Water-Reducing Polycarboxylate SuperplasticizerCore grade

Overview

This high-range PCE is copolymerized from HPEG / TPEG / EPEG polyether macromonomers and unsaturated carboxylic acids. It disperses cement particles through backbone adsorption combined with side-chain steric hindrance. Compared with naphthalene-based products it works at lower dosage with higher water reduction, and its molecular structure can be tailored on request.

Key benefits

• High water reduction enables low w/b high-strength concrete (C50 and above)
• Low dosage with minimal effect on setting time; balanced early and later strength
• Chloride-free — no risk of rebar corrosion, suitable for reinforced and prestressed elements
• Good compatibility with fly ash and GGBS

Application notes

Always run a cement compatibility test to determine the optimum dosage. Add by delayed or simultaneous addition with a minimum of 60 seconds mixing. Verify compatibility before combining with other admixtures, and never blend directly with naphthalene-based products.

Typical uses

Ready-mix concrete, high-strength concrete, pumped concrete, mass concrete and structures requiring high durability.
