Early-Strength Polycarboxylate Superplasticizer

Overview

Through molecular design combined with an early-strength component, this grade accelerates early cement hydration while cutting water demand (raising density), delivering rapid early strength gain while later strength keeps growing.

Key benefits

• Demoulding strength reached in 12–16 hours, raising mould turnover
• Compatible with steam curing, no strength regression after curing
• Chloride-free: no corrosion of reinforcement or steel moulds
• Effective early strength gain also at low temperatures

Application notes

For steam curing, hold 2–4 h before heating, ramp at no more than 20 °C/h and hold at 60–80 °C. Dosage must be confirmed by trial against cement type and ambient temperature.

Typical uses

Precast elements, piles, sleepers, tunnel segments, cold-season concreting, emergency repair works.

Typical applications

• Precast elements
• Piles
• Tunnel segments
• Low-temperature concreting
