The combined effect of chlorides and sulphates present in water and aggregates on properties of concrete
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% SO3) with chloride contents in water (50, 750, 1000, 3000 and 6000 p.p.m. as Cl−) were used. The compressive strength was lower for concrete with higher sulphate contents at early ages. Small additions of sodium chloride to the mixing water decreased the compressive strength of concrete, particularly those with a low sulphate content.
