MasterRoc HCA 20 (formerly Delvo Crete Stabilizer)
The manufacture and use of shotcrete has traditionally been linked to many drawbacks.
Shotcrete mixes are high performance materials and their useful life is only a few hours. Long transportation and storage times as well as work interruptions in the shotcrete process cause quality loss, decreased productivity and wasted material.
MasterRoc HCA 20 is the adoption of DELVO® technology - a major breakthrough by BASF in concrete technology - for shotcrete.
MasterRoc HCA 20 is a unique chemical admixture that controls the dynamics of cement hydration, suspending the process. Using one of BASF’s shotcrete accelerators, the hydration process can be reactivated hours or even days later.
