DETERMINATION OF TOTAL AND SOLUBLE CHLORIDES IN CONCRETE

Methods to determine chloride concentrations have been evaluated using aqueous solutions and hardened concrete samples and are shown to be sufficiently accurate for solutions. Dilute acid extractions do not completely dissociate chlorides from powder concrete samples and the strength of the acid extraction regime gives rise to different measured chloride contents. On the other hand, the water-soluble chloride content is shown to be independent of the method of extraction, providing the extraction period is equal to or greater than 24 hours. Chloride contents in concrete can be expressed as either total, acid-soluble or water-soluble proportions. (A) (Author/TRRL)
