CALCIUM FORMATE
TECHNICAL GRADE
High-purity crystalline organic salt designed to accelerate initial cement setting, boost early 1-day compressive strength, and prevent rebar corrosion in concrete.
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.
Calcium Formate Technical Grade Performance Metrics
Review key physical parameters, purity thresholds, and chemical assay parameters for Calcium Formate Technical Grade powder below.
≥ 98.5% Powder
High-purity white crystalline powder ensuring maximum reactive calcium content per kilogram.
0.00% (Non-Corrosive)
100% chloride-free formulation ensuring zero risk of rebar pitting or corrosion in reinforced concrete.
Concrete & Tile Adhesive Accelerator
Accelerates hydration, shortens set time, boosts 1-day strength, and enables cold-weather concreting.
Calcium Formate delivers rapid early strength development, complete rebar safety, and cold-weather setting performance.
Accelerated Setting Time
Drastically shortens initial and final cement setting times, allowing faster mold stripping and early foot traffic.
Enhanced 1-Day Strength
Boosts 24-hour compressive and flexural strength by up to 30–50% in precast and repair mortars.
Zero Rebar Corrosion
Contains 0.00% chloride ions ($\text{Cl}^-$), protecting steel rebars and post-tensioned cables against degradation.
Cold-Weather Concreting
Maintains rapid cement hydration at low ambient temperatures ($0^\circ\text{C}$ to $10^\circ\text{C}$), preventing frost damage.
Anti-Efflorescence in Grouts
Binds free lime during early hydration, suppressing white salt efflorescence on tile adhesive surfaces and wall renders.
Universal Cement Compatibility
Fully compatible with Ordinary Portland Cement (OPC), Pozzolanic (PPC), Slag (PSC), and High-Alumina cements.
Wely incorporated into dry-mix construction mortars, ready-mix concrete, precast elements, and industrial processing.
Tile Adhesives and Mortars
Essential early-strength accelerator for thin-bed C1/C2 tile adhesives, non-shrink grouts, and floor screeds, accelerating walkability.
Precast Concrete & Cold Weather
Accelerates formwork turnover in precast yards and prevents setting delays during winter concreting operations without steam curing.
Repair Mortars and Shotcrete
Provides fast initial stiffening and rapid mechanical strength development in structural patch repair formulations and tunneling shotcrete.
Leather Tanning and Industrial Chemicals
Used as a masking agent in chrome tanning to improve leather grain penetration and as an eco-friendly binder in flue gas desulfurization.
