C-FAST

Function: admixture accelerating the setting time of cement and improving the workability of the concrete mix.

Application: ready-mix and precast concretes, particularly recommended for work at low temperatures and for concretes at risk of freezing.

Properties: significantly increases early strength, shortens the curing period in moulds and formwork, accelerates hardening and setting, lowers the freezing temperature of water, and allows slower-setting cements to be used in precasting.
