This test method is used in making a preliminary determination of the acceptability of fine aggregates with respect to the requirements of Specification C33 that relate to organic impurities. The principal value of this test method is to furnish a warning that injurious amounts of organic impurities may be present. When a sample subjected to this test produces a color darker than the standard color it is advisable to perform the test for the effect of organic impurities on the strength of mortar in accordance with Test Method C87. |
