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. 
Using Procedure

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 nitriteblends have been used extensively, with the added advantage of anti-corrosion properties claimed for their use

Remarks
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
