The sand equivalent is the ratio of the height of sand to the height of clay times 100. Significance This test assigns an empirical value to the relative amount, fineness, and character of clay-like material present in the test specimen.

Note 2—Tests on damp samples will generally give lower sand equivalent values than tests on oven-dried samples. It is permissible not to dry the sample to save time, but if the test values are near or below the specified minimum, retest the sample in the oven-dry condition. 4.1.3 Remove sample from oven and allow it to cool to room temperature.

It has been found that the activity as well as the amount of the minus no. 200 mesh fraction of concrete aggregates affects the properties of concrete. Both activity and amount are re flected in the sand equivalent value but not in the loss by decan tation. Clay contaminants in concrete aggregate affect concrete properties primarily through ...

1.1 This test method is intended to serve as a rapid field-correlation test. The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-size or plastic fines and dust in granular soils and fine aggregates that pass the 4.75-mm (No. 4) sieve. The term "sand equivalent" expresses the concept ...
