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.
