China Factory Direct CAS 544-17-2 CF Calcium Formate for Concrete Accelerator

Calcium formate acts as a concrete accelerator. It speeds up cement hydration, reducing setting time by 20-40% and significantly improving early compressive strength. This makes it especially valuable for cold weather concreting, precast elements, and projects with tight construction schedules. Unlike chloride-based accelerators, calcium formate has a neutral pH and does not cause corrosion to steel reinforcement.

Both are concrete accelerators, but calcium formate is non-chloride based with a neutral pH, making it safe for steel reinforcement. Calcium chloride accelerates faster but can cause corrosion to rebar, limiting its use in reinforced concrete. Calcium formate also offers better workability and consistent setting performance without the risk of efflorescence or scaling.

No, calcium formate accelerates early strength development without compromising ultimate strength. It improves compressive strength at early ages (1-7 days) while maintaining or even slightly enhancing long-term strength (28 days and beyond). This makes it ideal for precast concrete where rapid demolding is required, without sacrificing final structural performance.

Yes, calcium formate is safe for reinforced concrete. Unlike chloride-based accelerators, it is non-chloride and has a neutral pH (6.5-7.5 in 10% solution), posing no corrosion risk to steel reinforcement. It is widely used in bridges, parking structures, and other reinforced concrete applications where corrosion protection is critical.

Calcium formate is available in 25kg laminated bags, 500kg, and 1000kg jumbo bags. Store in a cool, dry, well-ventilated area, away from moisture and direct sunlight. Keep containers tightly sealed when not in use. Under recommended conditions, shelf life is 24 months. The product's free-flowing nature ensures it remains easy to handle even after storage.
