Cement Set Accelerator


ZC-2 is an effective accelerator where high early strength concrete is desired in ready-mix cement products and shotcrete applications. It works well with Portland cement, slag cement, dam cement and early high strength cement. The viscosity, tensile strength and bonding strength of cement are increased by adding ZC-2. During shotcreting, it reduces rebound rate and dust density, creating a better working condition compared to other types of accelerator.
