Abstract
This paper considers the occurrence of chlorides in hardened concrete. It shows how the presence of pulverized-fuel ash (pfa) is potentially beneficial in reducing the proportion of water-soluble chlorides. This effect increases with concrete maturity. Acid- soluble chloride proportions are shown to be variable depending on the rigour of the acid-extraction techniques. Contrary to this, water- extraction of chlorides appears to be less variable, provided that the extraction period is greater than about 24 hours. (A)
