The test for acid-soluble chlorides (ASTM C 1152) treats crushed material with nitric acid rather than water. Almost all of the chlorides present in the concrete are detected, whether they are bound or are available to cause corro-sion. Because the test method finds all chlorides, limits based upon acid-soluble chloride content are higher than

The acid-soluble chloride will represent essentially the total chloride ion content of the material, much of which is not water-soluble. Of the total (acid-soluble) chloride content only about 50% will be water-soluble [2]. An alternate to the direct testing for the water-soluble chloride ion by ASTM C1218 [3] has been proposed by NRMCA [4,5].
