Magnesium oxychloride cement (MOC, Magnesia / Sorel’s Cement), discovered by Sorel S.T. in 1867 and has versatile cementing characteristics. Investigation pertaining to the effect of temperature of gauging solution on setting characteristics and moisture ingress (steam test) of Magnesium oxychloride cement (MOC) has been observed by authors in this paper. The experimental works have been carried out on different dry-mix compositions 1 : 0, 1 : 1, 1 : 2 & 1 : 3 and on different temperatures 30oC, 35oC, 40oC & 45oC at 28o Be density of gauging solution (g.s.). It has been recorded that initial and final setting time of cement blocks decreased with increasing temperature of gauging solution in the each dry-mix composition. The increasing trends of both setting time with increasing ratio of inert filler (dolomite) have also been noticed at a particular temperature. Results shown that both setting times of cement blocks are directly proportional to the ratio of inert filler in the dry-mix composition but inversely to temperature of gauging solution. The temperature of magnesium chloride solution (gauging solution) shown the great effect on the moisture ingress of MOC.
