PROFAST S/SB

PROFAST S/SB is a cement system accelerator that meets the UNI EN 934-2 standard, which outlines the requirements for the Manufacturing and Control Plan and product characteristics in the construction sector. PROFAST S/SB activates the setting process of cement in injection mixtures and increases the viscosity of cement mixtures, even those with a high water-to-cement ratio and high fluidity. It is commonly used in tunnel construction with TBM machines, particularly in cement mixtures where the setting has been previously delayed using the additive Protard G.
