Gypsum Retarder

Industrial cement often contains a higher ratio of gypsum than other concrete mix designs. This means that industrial concrete tends to have a rate of false set. False set occurs because the gypsum in the cement overheated during the manufacturing process. When this overheated gypsum mixes with water it can start to form plaster of Paris, making it appear as though the concrete is starting to set up. The best way to reduce false setting problems in concrete is to delay or neutralize the gypsum. That’s where Fritz-Pak’s Gypsum Retarder comes in handy. This product delays the setting time of gypsum to reduce false set problems and improve the performance of gypsum-based types of cement and concrete. It does not contain any hazardous materials and does not give off an offensive odor. For more information about this product or any of our other admixtures, follow our social media channels.
