Portuguese Calcium Formate Cement Accelerator
Construction Grade Calcium Formate
Calcium formate (Ca(HCOO)₂) is a white crystalline powder that acts as a highly effective cement accelerator in concrete and dry mix applications. Calcium formate acts in the early stages of cement hydration and is the additive of choice for:
Accelerated setting time
Improved early compressive strength
Cold weather concreting
Reduced project delays
Whether you’re working with high-performance concrete, fast-setting mortar or winter tile adhesive, calcium formate cement can add speed and consistency to your production.
| Property | Specification |
|---|---|
| Chemical Formula | Ca(HCOO)₂ |
| Appearance | White crystalline powder |
| Purity | ≥ 98% |
| Moisture | ≤ 0.5% |
| pH (10% solution) | 6.5 – 8.0 |
| Bulk Density | 900–1000 kg/m³ |
Recommended Applications
- Ready-Mix Concrete
- Precast Concrete
- Grouting Compounds
- Tile Adhesive
- Dry-Mix Mortar
- Self-Leveling Underlayment
- Gypsum-Based Products
- Cold Weather Concrete Projects
Typical Dosage and Use Guidelines
| Product Type | Recommended Dosage | Function |
|---|---|---|
| Cement/Concrete | 0.5%–2.5% by weight of cement | Set acceleration & early strength |
| Dry-Mix Mortar | 0.3%–1.5% | Quick setting & anti-frost effect |
| Tile Adhesive | 0.2%–1.0% | Anti-slump & fast drying |
| Gypsum-Based Material | 0.5%–1.5% | Quick hardening |

Why Use Calcium Formate in Cement and Concrete?
Fast Initial and Final Setting Time
By accelerating the hydration of tricalcium silicate (C₃S) in cement, calcium formate significantly reduces the set time, from hours to minutes, depending on dosage and temperature.
Works in Cold Temperatures
Winter concrete pours can be risky and slow. Calcium formate ensures proper curing and setting even at 5°C or below, preventing cracks and delays.
Non-Corrosive, Chloride-Free
Unlike calcium chloride, calcium formate is safe for steel reinforcement, making it ideal for precast, bridges, and infrastructure projects.
Boosts Early Strength Development
Improves compressive strength at 8 hours, 1 day, and 3 days, which is critical for early demolding, fast-track construction, or quick traffic opening.
Enhances Workability and Surface Quality
Reduces bleeding and segregation, leading to smoother finishes, fewer surface defects, and denser microstructure.
Performance Comparison:Calcium Formate vs. Traditional Accelerators
| Feature | Calcium Formate | Calcium Chloride | No Accelerator |
|---|---|---|---|
| Accelerates Early Strength | ✅ | ✅ | ❌ |
| Chloride-Free (Steel-Safe) | ✅ | ❌ | ✅ |
| Cold Weather Performance | ✅ | Moderate | Poor |
| Reduces Set Time | ✅ | ✅ | ❌ |
| Environmentally Friendly | ✅ | ❌ | ✅ |
Looking for more than just set acceleration? Calcium formate also improves freeze-thaw resistance, surface finish, and dimensional stability.

Real World Case: Precast Concrete
A precast concrete plant in Europe faced curing delays during winter. After incorporating 1.5% calcium formate, they:
Reduced set time by 40%
Increased 1-day strength by 30%
Shortened mold release time by 6–8 hours
Result: Higher output, faster rotation, and better schedule control.
