COMPARATIVE SULPHATE RESISTANCE OF SRPC AND PORTLAND SLAG CEMENTS

ByJ.J.KOLLEK, J.S.LUMLEY

It is only a comparatively small amount of concrete (estimated to be about 4% of total) that is designed to withstand the attack of sulphates. However, although the volume is small, such concrete is used in critical parts of major structures and as such justifies our more than average attention. The consequences of sulphate attack are expansion, cracking, loss of strength and with time, under extreme conditions, complete disintegration.
