Calcium Chloride Accelerators vs Non-Calcium Chloride
Jan 31 2019 · Accelerators should be used when ambient temperature approaches freezing conditions and when an increase in concrete strength is required at an early age. However the main reason concrete contractors use accelerators is to reduce the set time of the concrete. During cold weather it takes longer for concrete to reach initial set.

Calcium chloride (CaCl2) has the ability to accelerate cement hydration and reduce set time by as much as two thirds. Research has shown that a 2 addition rate has an equivalent cure strength at 50°F as plain concrete at 70°F. Set times below 50°F will be longer but the accelerated cure rate will still be greater than that of plain concrete.

Concrete AcceleratorsDefinition Examples and Effects
Examples of Accelerators in Concrete Calcium chloride is a common accelerator used to accelerate the time of set and the rate of strength gain. It should meet the requirements of ASTM D 98. Excessive amounts of calcium chloride in concrete mix may result in rapid stiffening increase in drying shrinkage and corrosion of reinforcement.
