Abstract The combined effect of sulphates present in aggregates and high levels of chloride ions in the mixing water on some properties of concrete was studied. Different amounts of sulphates in sand (0.38, 0.50, 0.75 and 1.0% SO 3) with chloride contents in water (50, 750, 1000, 3000 and 6000 p.p.m. as Cl −) were used.
