Calcium Formate
-
Standard Chemicals International supplies a free-flowing fine powder form. It can be found in technical, industrial, and food-grade specifications as it is soluble in water and is a source of calcium ions and formic acid.
Calcium Formate, besides its use as a concrete accelerator that can improve concrete’s setting and curing time and is often used in self-leveling compounds and mortars, is also used as a feed supplement for livestock and as a source of calcium and formic acid in various industrial applications.
Calcium Formate’s non-chloride nature makes it an environmentally friendly alternative to traditional chloride-based accelerators. It is commonly used in construction applications where fast-setting times are required and is available in various grades to meet the needs of different industries. It accelerates cement hydration, leading to faster setting times and increased early strength. It can also reduce the water demand of the mixture, leading to improved workability and increased final strength.

Calcium Formate is a salt of formic acid and calcium, and it is commonly used in the oil and gas industry in both cementing and fluid loss/circulation applications.
In cementing applications, Calcium Formate is used as an accelerator, which means it speeds up the setting and hardening of the cement. This is particularly useful in colder environments where the curing process can be slower. Calcium Formate has the added benefit of accelerating the cement’s initial and final set, which can be crucial when quick cementing is needed. Calcium Formate is compatible with other additives commonly used in oil well-cementing applications.
In fluid loss/circulation applications, Calcium Formate is used as a fluid loss additive to help prevent the loss of drilling fluids into the formation. Calcium Formate effectively reduces fluid loss, particularly in high-temperature environments, and it can also help stabilize the rheological properties of the drilling fluid. In addition to its fluid loss control properties, Calcium Formate can also act as a pH buffer, helping maintain the drilling fluid’s pH within a desirable range.
