Product Overview
Concrete Accelerator is a chloride-based liquid admixture specially formulated for PCC (Precast Concrete) works to accelerate setting time, attain early strength, improve productivity, and deliver smooth surface finish with enhanced quality.
This high-performance accelerator is designed specifically for manufacturing strong and quality concrete blocks, hollow blocks, paving blocks, and design tiles. The formulation ensures exceptionally smooth surfaces while significantly improving the overall quality of precast elements.
Beyond precast applications, our concrete accelerator is also suitable for mass concreting under seawater conditions and during cold weather construction, where rapid setting and early strength development are critical for project success.
Primary Applications
- • Concrete blocks
- • Hollow blocks
- • Pavement blocks
- • Design tiles
- • Precast concrete elements
- • Mass concreting (seawater)
- • Cold weather construction
- • High productivity applications
