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

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 cement hydration.

  • Annulus grouting (TBM)
  • Cementitious injection systems
