Calcium Formate

CAS: 544-17-2

Calcium Formate is a calcium salt, used primarily as an additive in different industries, for instance, construction, in which case it improves the properties of materials. Derived from the reaction of calcium carbonate with formic acid, Calcium Formate stands out from other additives by its capacity to slow down the setting of concrete and improve resistance to water. The construction industry started using the compound in the mid-20th century, and the role of the additive has gained importance as a result of a number of advantages for concrete and mortar applications.

Not only does Calcium Formate serve as a useful additive in construction, but it has also been effectively utilized in inducing lower pollutant emissions for use in industrial processes.

Applications in Construction

Calcium formate is a popular additive used in the concrete and mortar industry. This product primarily benefits construction materials in the following ways:

Set retarding: This property entails the control of the setting time of concrete to increase working time when the temperature is high.

Improved strength: It increases the strength of concrete in wet conditions or under high-stress conditions.

Reduced porosity: It decreases the absorption of water into concrete structures and thus helps avert damage due to freezing.

Other Applications

Besides construction, Calcium formate is applied in agriculture for crop protection to improve pesticide adhesion. It is used as an additive in the manufacture of greases and lubricants to impart resistance to high temperatures. It is a useful anti-scorching agent in plastics and rubber manufacture. Calcium formate acts as a coagulant in water treatment for the subsequent removal of other impurities; hence, it improves water quality, particularly in industrial treatment systems. The textile industry employs calcium formate in the manufacture of synthetic fibers and as a bleaching or finishing agent in enhancing the properties of fabrics.
