THE SULPHATE RESISTANCE OF PORTLAND AND BLASTFURNACE SLAG CEMENT CONCRETES. IN: DURABILITY OF CONCRETE. SECOND INTERNATIONAL CONFERENCE. AUGUST 4-9, 1991, MONTREAL, CANADA. VOLUME II

Laboratory tank tests were used to assess the sulphate resistance of a series of Portland and blastfurnace slag cement concretes. Following different early curing regimes, 100 mm concrete cubes were stored in tanks of sodium and magnesium sulphate solutions for 5 years. The concrete cubes were photographed and their sulphate attack ratings and compressive strengths measured at 1, 2 and 5 years. The results showed that concretes made with ground granulated or pelletized blastfurnace slag and Portland cement generally had good sulphate resisting properties when the slag content was 70 percent and above. The significance of the pre-curing regime, the tricalcium aluminate (C sub 3 A) content of the Portland cement and alumina level of the slag on the sulphate resistance of concrete are discussed.
