Abstract
Four sulfate resisting binder types have been examined by immersing mortar specimens (40∗40∗160 mm, sand/binder ratio = 3.0), in magnesium sulfate solutions. Strength, mass and length changes have been recorded over a period of 2 years. Differences in performance between SRPC and mixer combinations PC/blastfurnace slag, PC/fly ash and PC/silica fume binders have been vonfirmed, and the general conclusion of the study is that the sulfate resisting Portland cements behaved significantly better than these other binders under the conditions of exposure adopted.
