Product Short Description: Calcium Di-formate Used in Building Materials, as Cement Additive
Product Description:
Calcium Formate supplier and exporter for Middle East - GULF and Oman, Sudan, Nairobi, Yemen.  Calcium Formate, being an organic admixture, is Nonabsorbent. Calcium Formate also used as Cement Additive and De-Icer agent.
Product Application:
Calcium formate reduced the initial and final setting times of CTB mixtures, while The addition of sodium sulfate relatively affects the setting times by accelerating both initial and final setting times with the increasing proportion of the content. 
Product Dose:

Two or more chemicals are often used in combination to increase the concentration and improve the performance of liquid admixtures, which are preferred to powders for accurate dosing of concrete. Calcium formate sodium nitrite blends have been used extensively, with the added advantage of anti-corrosion properties claimed for their use

Calcium Format Chemical Reactions
 
Calcium formate can be used to prepare solutions of other water-soluble formate salts. For example, the addition of nickel (II) sulfate to a solution of calcium formate results in the precipitation of insoluble calcium sulfate, leaving nickel (II) formate in solution:
 
Ca(OOCH)2 + NiSO1 → CaSO4 + Ni(OOCH)2
 
In a similar reaction, sulfuric acid reacts with calcium formate to provide low-cost solutions of formic acid:
 
Ca(OOCH)2 + H2 SO4 → CaSO4 + 2HCOOH
 
When heated, calcium formate decomposes to calcium carbonate and formaldehyde:
 
Ca(OOCH)2 → CaCO3 + HCHO
 
Continued heating at higher temperatures results in the breakdown of these decomposition products:
 
HCHO → CO + H2
 
CaCO3 → CaO + CO2
 
Calcium formate can be used as a low-cost reducing agent in the conversion of carboxylic acids to aldehydes. This process is an effective substitute for the troublesome Rosenmund reduction.
 
(RCOO)2Ca + (HCOO)2CA → 2RCH + 2CaCO3

Calcium Format Uses
 
Leather Tanning
 
Calcium formate is used extensively in the leather industry as a masking agent in the chrome-tanning process. The addition of calcium formate to the tannage formulation promotes faster, more efficient penetration of the chrome in the leather. Calcium formate can also be used as a replacement for formic acid in the pickling operation.
 
Cement Additive
 
As an additive to grouts and cement, calcium formate imparts a number of properties desirable in the final product, e.g. increased hardness and decreased setting time in comparison to ordinary cements. The addition of calcium formate is desirable for work at low temperature and for inhibition of corrosion of metal substrates. It is also effective in the prevention of efflorescence. When used in gypsum board, calcium formate functions as a fire retardant.
 
Silage Treatment
 
Calcium formate is commonly used as a component of an ensiling agent for silage treatment. The use of calcium formate in the silage suppresses the formation of side reaction products such as propionic acid, while promoting the formation of desirable lactic acid in anaerobic fermentation.
 
Gas Generation
 
A mixture of calcium formate with ammonium nitrate or with chlorate, perchlorate, peroxide, superoxide or permanganate of an alkali metal will rapidly evolve large volumes of gas when ignited. Because the released gases are cool, non-poisonous and non-irritating, they could be used for the inflation of automobile passenger restraint bags or other similar applications. gases are cool, non-poisonous and non-irritating, they could be used for the inflation of automobile passenger restraint bags or other similar applications.
 
Flue-gas Desulfurization
 
SOx is abated in the flue-gases from the burning of high-sulfur fuel oil if the oil has been emulsified with a solution containing calcium formate before burning. As much as 95% of the SOx is removed.
 
Safety Explosives
Calcium formate can be used as the fuel component in explosives designed to have improved deflagration behaviour. Such explosives are suitable for use in hazardous atmospheres often encountered in coalmines.
 
De- icing agent
 
Mixtures of Calcium Formate with urea are excellent agents for the melting of ice. Less corrosion of steel and cement surfaces is observed than with other de-icers.
 
Other uses
 
Calcium formate can be used as an additive to improve solution stability of various resins, as a corrosion inhibitor in moulding and wire-drawing operations, or as a catalyst in place of calcium acetate.
 
Buffered solutions
 
Buffered solutions exhibiting a range of pH values can be obtained by varying the ratio of formic acid to the salt as in table below:

Formic Acid 0.1N, ml 90 80 70 60 50 40 30 20 10
pH 2.81 3.10 3.32 3.50 3.67 3.80 4.0 4.23 4.58
 
Animal Feed Additive
 
Calcium formate is an organic salt suitable for use in pig and poultry diets. It acts as a feedstock preservative and has an acidifying effect on the gastro-intestinal tract, which promotes good gut-health. The efficiency of pig and poultry feedstock digestion is dependent on the indigenous micro-organism concentration in the gastro-intestinal tract. With the approaching ban on the use of prophylactic antibiotics in animal feed as a means to control disease and promote growth, alternatives are needed to limit the proliferation of pathogenic bacteria in the gut which can impair feedstock digestion as well as cause enteric diseases such as E. Coli and Salmonella. Acidifiers such as calcium formate preserve the feedstock before consumption and lower the pH in the gastro-intestinal tract, creating unfavourable conditions for these bacteria to grow.
