Plasticizer that adjusts setting-time
POLIRETARD HC is a fluidizing admixture with retardant action specifically designed for long- distance transport. It prevents cold joints in large, mass concrete casts. POLIRETARD HC is specially formulated to prepare concrete when it is necessary to adjust and delay initial setting time because it reduces and controls the heat of concrete during hydration.
