What is calcium formate
Calcium formate is a calcium salt of formic acid. A white crystal powder.
It’s a construction additive. Calcium formate in cement effectively extends the opening time and improves adhesion. It helps to improve water stability, flexibility, and homogeneity. Thus it’s widely used in concrete and cement to speed up the working process.
Calcium formate is also used as a preservative in animal feed within the EU region, but not in human food. It’s stable under room temperature, inflammable, and forms cube crystals.
Calcium formate used in construction
Calcium formate in concrete. It’s an additive without a corrosive effect on reinforcement. The primary role is to accelerate the hydration of tricalcium silicate in cement. And improve the cement strength at an early stage. The majority influence of calcium formate accelerator depends on tricalcium silicate content in cement. The lesser the tricalcium silicate added, the better the strength effect. Furthermore, it will maintain the strength of the mortar at a later stage. It has an excellent anti-freezing impact.
Calcium formate in cement. The calcium formate concrete accelerator comes with a 2-in-1 function. It speeds up the cement setting process and avoids delaying the setting speed due to low temperatures in winter construction. At the same time, increase the cement intensity, especially at the early stage. It does the same in high temperatures as well.
Calcium formate uses
WOTAI Calcium formate is primarily used in concrete, dry mortar, and tile adhesive. It influences the setting and hardening time by accelerating the formation of tricalcium silicate. Calcium formate can modify the initial workability of wet mortar according to the usage amount.
Calcium formate allows concrete to be set within 4 hours under normal conditions. While assuring the early strength of mortar or concrete. It increases mortar strength without compromising other technical properties. Calcium formate is compatible with other additives.
Calcium Formate is a construction additive designed to improve the qualities and properties of tile adhesives significantly. Calcium formate joint application effectively prolongs open time, improves adhesion and is a highly efficient strength accelerator, which is a vital indicator for tile mortars.
The EU has evaluated calcium formate as a preservative in all animal species. And it is not expected to adversely affect the safety of target animals when used in recommended doses. The demand for calcium formate as a feed additive is expected to grow significantly in the coming years.
Calcium formate characteristic values
WOTAI calcium formate is sold very well in oversea countries, such as Europe, America, and Africa, and is very popular in many industrial fields, such as animal feed and construction.

Calcium formate manufacturing process
Calcium formate is manufactured by reacting dilute sulfuric acid and calcium carbonate, or calcium hydroxide, to form a calcium formate solution. After filtering out the insoluble composition, the filtrate is concentrated and crystallized. Calcium formate is afterwards centrifuged and dried. However, this method is complex, with high energy consumption and production cost.
Another method is called the quicksand production technique. Only use formic acid and calcium carbonate as raw materials. It’s a short process and easy to operate, with low energy consumption and a lower budget. The final product is white, smooth-flowing crystal particles, good quality and high purity.

Calcium formate can significantly increase the growth of calcium alumina in the early stage of cement hydration and accelerate the hydration of C3S to improve the early strength of cement products but has little effect on the setting time of cement, and the physical properties of calcium formate are stable at room temperature, not easy to agglomerate, more suitable for use in dry mortar, with good freeze-thaw resistance, and can be negative temperature construction.
Yes. calcium formate solubility: ± 0.04 g/100 g water.
Under normal circumstances, there is no dangerous reaction has been found.
Researchers confirmed that calcium formate could be used as feedingstuffs preservative for all animal species.
