Riteks HydraStop™ is a hydration stabilizer which helps maintain slump and proper set times of freshly produced concrete over extended haul times and increased ambient temperatures. Hydra-Stop is used to offset issues caused by extended haul times, excess drum revolutions or the effects of temperature and time. HydraStop is especially helpful in the summer months when hydration is accelerated due to higher ambient and mix temperatures. HydraStop aids in controlling concrete temperature when a maximum mix temperature is specified. Concrete performance properties are maintained while exceeding the requirements of ASTM, AASHTO and CRD specifications.
