The sand equivalent test is measured using ASTM D 2419. This test separates out a fine aggregate sample's sand and plastic fines and dust portion to determine the content of the latter. Lower sand equivalent values indicate higher plastic fines and dust content. In the soundness test, it is measured using ASTM C 88. Steel slag is highly resistant
