Applications:
– Concrete placement in heavily reinforced structures, narrow sections, and high-rebar density elements.
– Cold-weather concreting in winter or cold regions to prevent freezing.
– Production of precast and prestressed concrete elements.
– Concrete works for slabs, foundations, columns, walls, bridges, dams, canals, etc.

Benefits:
• Increased concrete workability (higher slump).
• Accelerated setting time, reduced formwork removal time, and faster load application.
• Prevention of concrete freezing.
• Improved pumping ease and enhanced concrete cohesion.
• Faster placement time.
• Compatible with all cement types.
• Reduced concrete permeability.
• Potential reduction in mixing water.
• Increased concrete strength.
• Suitable for slipform concreting.
• Chloride- and nitrate-free; non-corrosive to reinforcement and concrete.

Dosage:
Recommended dosage is 0.5% to 1.3% of cement weight, depending on materials and mix design. Field tests are advised to determine precise dosage.

Application Method:
1. Mix with all or part of the concrete mixing water, then add to the mix.
2. Add to ready-mix concrete, mix thoroughly for 3 minutes, then begin placement.
