S-FAST

Function: admixture that accelerates the setting time of cement and improves the workability of concrete.

Application: ready-mix and precast concrete, especially recommended for concreting in low-temperature conditions and where there is a risk of freezing.

Properties: significantly increases early strength, reduces curing time in the mould, accelerates the hardening of concrete, lowers the freezing point of water, and allows the use of slower-setting cements in precast production.
