Abstract
1447357 Calcium sulphate setting IMPERIAL CHEMICAL INDUSTRIES Ltd 22 Oct 1973 [31 Oct 1972] 50155/72 Heading C1A The setting time of calcium sulphate hemihydrate and a preselected amount of water is controlled by mixing with part of the water required for setting at least one calcium compound which will react with sulphuric acid to form calcium sulphate, mixing sulphuric acid and the remainder of the water with the calcium sulphate and water mixture, allowing the sulphuric acid and calcium compound partially to react and at least 30 seconds after the addition of the acid mixing solid calcium sulphate hemihydrate with the reacting mixture, the total amount of water in the final mixture being equal to the preselected amount. The calcium compound may be at least one of the hydroxide, oxide, carbonate, chloride, or nitrate.
