Riteks SYAD™40 is a set retarding water reducing multi-component admixture for concrete. It is designed to facilitate the placing and finishing of concrete while providing control over the set time. SYAD 40 improves pumpability of concrete and is especially beneficial during hot weather concreting operations when control of setting time and maintenance of placeable consistency are essential. SYAD 40 provides superior finishability on all flatwork and pre-cast surfaces.
