PROTARD G

PROTARD G is a setting retarding additive with a fluidifying effect, designed for cementitious injection systems in the construction sector. It complies with the UNI EN 934-2 T8 standard, which specifies the requirements for the Manufacturing and Control Plan and product characteristics, particularly for retarding additives. PROTARD G is widely used in tunnels constructed with TBM machines, where mixtures need to maintain workability over extended periods. It is also suitable for cementitious mixtures that require subsequent acceleration of setting time, using additives like PROFAST S and PROFAST SB.
