The results of the
study indicate that while performance of all blended cements, particularly those made
with silica fumes, was generally excellent yet their performance in MgSO4 solution was
not satisfactory [Amoudi et al., 1995]. Previous studies carried out by Rasheeduzzfar et
al., [1994] and Cohen et al., [1988] on performance of blended Portland cement in
magnesium sulfate and sodium sulfate solution arrived to the same conclusions.
