    1996-2-1 · Your answer regarding permissible levels of chlorides and sulfates in aggregate might be OK for Saudi Arabia but certainly not for most of the United States. A limit on NaCl is meaningless: Does one measure sodium, or chloride, or both? Don't other chlorides count? What if both the coarse and fine aggregates contain chloride?

    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
