INFLUENCE OF PFA ON PROPORTION OF FREE CHLORIDES IN SALT CONTAMINATED CONCRETE. CORROSION OF REINFORCEMENT IN CONCRETE. PAPERS PRESENTED AT THE THIRD INTERNATIONAL SYMPOSIUM ON "CORROSION OF REINFORCEMENT IN CONCRETE CONSTRUCTION", BELFRY HOTEL, WISHAW, WARWICKSHIRE, MAY 21-24, 1990

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) For the covering abstract of the conference see IRRD 831449.
