Flo-Aid ACC is a calcium chloride-based accelerator for cementitious concrete or grout. Flo-Aid ACC reduces the amount of time until initial and final set. It can be used in applications that require early hardening or increased early strength, to expedite production. Flo-Aid ACC can be used in cold weather to prevent delayed setting time. Flo-Aid ACC meets the requirements of a Type C, accelerating admixture according to ASTM C 494. Calcium Chloride is corrosive and should not be used in steel-reinforced concrete. Use of calcium chloride may be limited or prohibited by code. Always consult with the engineer of record before use.
