Mix one teaspoon of dry USG standardStrength Retarder strength retarder with five fluid ounces of water to prepare a solution that will extend the set time of 100 pounds of gypsum plaster by 3040 minutes or more. For larger quantities, mix an entire 11/4 lb. container of USG ...
What is the purpose of adding gypsum in cement?
Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the [.]

clinker SO3 vs Gypsum
· Re: clinker SO3 vs Gypsum. Yes, the SO3 present in the clinker will play a role as setting retarder. But as previous poster noted, the effect is dependant on the solubility of sulphate. If it is linked to alkalis, it will be very solube and active, if not, CaSO4 will not be very active. I know a plant where gypsum addition in the cement is ...
