Accelerator of sprayed concrete

Accelerator admixtures of shotcrete are used to accelerate initial setting or instant setting of shotcrete. These admixtures improve the compressive strength of the early ages, adhesion, reduce the shrinkage of concrete from the surface and resistance to freezing.These materials in the process of dry shotcrete, while reducing material shrinkage, lead to a reduction in the amount of dust and an increase in premature resistance. In the spraying process, fast setting and early resistance are reasons for using these products.The main application of accelerator admixtures for shotcrete is: shotcrete is for stabilizing slopes and excavations, lining tunnels and excavations.
