Calcium Chloride Home : Frequently Asked Questions : Concrete Acceleration Application Questions

Are there applications where calcium chloride should not be used as a concrete accelerating admixture due to potential corrosion issues with reinforcing steel?

It is recommended that the most recent reports from the following American Concrete Institute (ACI) committees be consulted. These ACI documents discuss the amounts of calcium chloride that are allowed in concrete under various exposure conditions and they review certain conditions, in which calcium chloride should not be used.

ACI 201 Durability of Concrete
ACI 212 Admixtures for Concrete
