The Role of Calcium Chloride in Concrete Cross ...

Jan 24, 2020  Calcium chloride accelerates cement’s rate of hydration. A reduction in setting time helps protect freshly placed concrete. The effect is most noticeable in cool weather. Ready-mixed concrete sets more slowly at temperatures below 70°F, and even more so between 30°F and 50°F. This means concrete construction can continue in the fall and ...

Acceptable Use of Calcium Chloride in Concrete

the common dosage of 2% flake calcium chloride by weight of cement produces 0.98% chloride ion by weight of cement. Thus, if there were no other sources of chlorides in the concrete, the 1% limit on chloride ion in ACI 318 would still be met with a 2% dosage of flake calcium chloride when in-place concrete will be dry or protected from moisture ...
