Concrete AccelerationPeters Chemical Company
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.
