Calcium formate is another type of nonchloride accelerator used to accelerate the setting time of concrete. At equal concentration, calcium formate (Ca[OOOCH]
2) is less effective in accelerating the hydration of C3S than calcium chloride and a higher dosage is required to impart the same level of acceleration as that imparted by CaCl2 (Ramachandran 1984). An evaluation study of calcium formate as an accelerating admixture conducted by Gebler (1983) indicated that the composition of cement, in particular gypsum (SO3) content, had a major influence on the compressive strength development of concretes containing calcium formate. Results showed that the ratio of C3A to SO3 should be greater than 4 for calcium formate to be an effective accelerating admixture; and that the optimum amount of calcium formate to accelerate the concrete compressive strength appeared to be 2-3% by weight of cement (Gebler 1983). Calcium nitrate and calcium thiosulfate are also considered accelerators.

Local:
Calcium salt of formic acid. It is used in leather tanning, producing formic acid, concrete cure accelerator. It is used as a food additive and animal feed as a preservative (food additive E238). But its use is banned in some countries. It was used as a as a diuretic.

DESCRIPTION OF FORMIC ACID: Formic acid, also called methanoic acid), is  the simplest and has the lowest mole weight of the carboxylic acids, in which a single hydrogen atom is attached to the carboxyl group (HCOOH). If a methyl group is attached to the carboxyl group, the compound is acetic acid. It occurs naturally in the body of ants and in the stingers of bees. Functionally, it is not only an acid but also an aldehyde; it reacts with alcohols to form esters as an acid and it is easily oxidized which imparts some of the character of an aldehyde. Pure formic acid is a colorless, toxic, corrosive and fuming liquid, freezing at 8.4 C and boiling at 100.7 C. It is soluble in water, ether, and alcohol. It irritates the mucous membranes and blisters the skin. It is prepared commercially from sodium formate with the reaction of condensed sulfuric acid. Formic acid is used as a chemical intermediate and solvent, in processing textiles, leathers, electroplating, in coagulating latex rubber, and as a disinfectant.
