Fritz-Pak Mini Delayed Set is a dry powdered set retarder, packaged in a ready-to-use water-soluble bag. This product is designed for stabilizing residual concrete wash water or extending the setting time of concrete while improving concrete quality. Wash water or concrete, treated with the Mini Delayed Set, will be stabilized and may be reused after extended time periods. Concrete produced with stabilized wash water will result in performance characteristics equal to or superior to reference concrete. It not contain calcium chloride, nitrates, nitrites, or other potentially corrosive materials and is compatible with all standard concrete admixtures.
Use a small bag of delay set for emergencies, small concrete batches, concrete pump hoppers, or wash water stabilization. Normally one bag will delay the set of 1 yard of concrete for 1 hour. For wash water stabilization one bag is used for overnight stabilization.
