- Used to determine the presence of injurious organic impurities in fine aggregates that are to be used in hydraulic cement mortar or concrete.
- This test method is used in making a preliminary determination of the acceptability of fine aggregates with respect to the requirements of specification that relate to organic impurities.
- One procedure uses a standard color solution and the other uses a glass color standard.
- 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.
