SULFATE SPECIFICATIONS AS A CONSTRAINT TO GYPSUM ADDITION TO CEMENT AND POSSIBLE REPLACEMENT OF GYPSUM AS AN ADDITIVE. QUARTERLY TECHNICAL PROGRESS REPORT, DECEMBER 1978--JANUARY--FEBRUARY 1979

The objectives of the contract project are to develop comprehensive data on: (1) potential alternatives to gypsum for controlling set in commercial concretes; (2) additives to deter sulfate-induced expansion; and (3) the influence of clinker manufacturer on expansion potential in cements. This data will provide a basis for reconsidering the limitations currently imposed on sulfate contents in cements for reasons of soundness.
