Calcium Chloride

Calcium Chloride (CaCl2) is an inorganic salt. It is widely used in the building industry as an additive when mixing concrete, where it accelerates the setting time and improves cure strength, especially during cold weather. It also improves the workability of the wet concrete mix.

It has many other uses, such as for melting snow and ice and as a moisture absorber.</p><p>If concrete containing Calcium Chloride is directly in contact with steel reinforcing bars or RSJs corrosion may occur. For this reason structural steelwork should be treated with a resistant coating.
