Concrete Acceleration

Calcium chloride is a preferred additive for accelerating cement hydration and reducing set time for concrete applications, particularly in colder weather. It can enable concrete to be produced faster and allow jobs to be completed as quickly and economically as possible. Calcium chloride has the ability to accelerate cement hydration and reduce set time by as much as two-thirds. Research has shown that concrete produced with 2% calcium chloride exhibits 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. Calcium chloride can also improve mix workability, improve strength of air-entrained concrete, and reduce bleeding by enabling earlier final finishing.
