APP 025-02 (early strength & water-reducing type) is a high-performance polycarboxylate ether (PCE) superplasticizer that improves early strength in precast concrete.

Key features

• High water-reducing ratio (≥25%)
• Wide compatibility with cements, gravels and sands
• Early-strength type, suited to precast and tubular piles
• Low viscosity, suitable for pumping
• Improves concrete surface finish
