Non-Chloride Set Acceleration & Early Hydration Technology

Calcium Formate Technical Grade Crystalline Powder ($\text{Ca(HCOO)}_2$) is a premium-purity organic salt ($\ge 98.5\%$) engineered specifically as a non-chloride setting and hardener accelerator for Portland cement compositions, dry-mix mortars, tile adhesives, and precast concrete systems. By releasing highly active calcium ions ($\text{Ca}^{2+}$) into the aqueous phase during early cement dissolution, Calcium Formate significantly accelerates tricalcium silicate ($\text{C}_3\text{S}$) hydration, shortening initial and final setting times without risking steel reinforcement corrosion. Unlike traditional calcium chloride accelerators, Calcium Formate contains 0.00% chlorides, making it completely safe for reinforced concrete, pre-stressed beams, and architectural mortars. It excels in cold-weather concreting by overcoming temperature-induced hydration retardation, boosting 1-day compressive strength development, suppressing efflorescence in tile grouts, and serving as a masking agent in leather tanning and flue gas desulfurization.

Calcium Formate Technical Grade is 100% chloride-free, providing immediate 1-day compressive strength gains in C30+ concrete and CTA tile adhesives without inducing stress corrosion cracking on embedded steel rebars.

Frequently Asked
Questions (FAQ)

Get quick, technically vetted answers regarding Calcium Formate Technical Grade, dosage rates, cement compatibility, and rebar safety.

1. What is Calcium Formate Technical Grade and how does it function?
Calcium Formate Technical Grade ($\text{Ca(HCOO)}_2$) is a high-purity (≥98.5%) crystalline organic salt used as a non-chloride set accelerator in concrete and mortar. It releases active calcium ions during early cement mixing, accelerating silicate hydration and shortening setting times.
2. Why is Calcium Formate preferred over Calcium Chloride ($\text{CaCl}_2$)?
Unlike Calcium Chloride, Calcium Formate contains 0.00% chlorides, making it 100% non-corrosive. It accelerates cement setting without attacking embedded steel reinforcement, rendering it safe for reinforced concrete, pre-stressed structures, and architectural mortars.
3. What is the recommended dosage rate of Calcium Formate in cement mixes?
Typical dosage ranges from 0.5% to 2.0% by weight of total cementitious binder (500g to 2kg per 100kg of cement). Dosage can be adjusted based on ambient temperature, mix design, and desired early 1-day strength targets.
4. How does Calcium Formate perform in cold-weather concreting?
In cold temperatures ($0^\circ\text{C}$ to $10^\circ\text{C}$), cement hydration slows down significantly. Calcium Formate counteracts this retardation by accelerating early silicate hydration, restoring normal setting times, and protecting fresh concrete from early freezing damage.
5. How does Calcium Formate improve tile adhesive formulations?
In CTA tile adhesives and self-leveling floor screeds, Calcium Formate speeds up early curing, allowing tiles to gain rapid slip resistance and enabling faster grouting and foot traffic within 24 hours.
6. Does Calcium Formate reduce efflorescence in mortar and grouts?
Yes. By accelerating early silicate hydration, Calcium Formate binds free calcium hydroxide ($\text{Ca(OH)}_2$) into C-S-H gel structures, preventing lime migration to the surface and significantly reducing white efflorescence staining.
7. Is Calcium Formate compatible with superplasticizers and air-entrainers?
Yes. Calcium Formate is fully compatible with PCE superplasticizers, lignosulfonates, cellulose ethers, redispersible polymer powders (RDP), and air-entraining agents without causing chemical precipitation or phase separation.
8. How should Calcium Formate crystalline powder be stored?
Calcium Formate should be stored in original sealed poly-lined paper or PP woven bags in a cool, dry, sheltered warehouse to prevent ambient moisture absorption and lump formation.
