MasterRoc HCA 10 – Cement hydration control system for wet and dry sprayed concrete, grouting and cement injection



Formerly: DELVO CRETE STABILIZER



How does MasterRoc HCA 10 work?

MasterRoc HCA 10 is a high quality, liquid, non-chloride chemical admixture which can be used with dry and wet concrete mixes to control the dynamics of cementhydration. It delays hydration by suspending the hydration process and enables re-activation hours or even days later with no loss of quality in the hardened sprayed concrete. It is ideally suited for applications in:

  • Tunneling and mining
  • Temporary and permanent support
  • Slope stabilization
  • Annulus grouting (TBM)
  • Cementitious injection systems

What are the unique features of MasterRoc HCA 10?

  • Keeps concrete mixes workable for up to 3 days.
  • Complete use of wet and dry mixes – no waste disposal.
  • Provides considerable reduction of rebound and dust.

How does MasterRoc HCA 10 benefit customers?

  • Fully flexible delivery options for sprayed concrete mixes.
  • No cleaning of pumps or pipes during work interruptions.
  • Time and cost saving.​
