Sand Equivalent Test Method Explained and The Process

The sand equivalent test is used to limit the presence of clay material in the aggregate. The sand equivalent test ( AASHTO T176; ASTM D2419 ) is a rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate (or granular soils).

Quality Testing of Sand at The Construction Site for The Concrete. There are different methods for testing the quality of sand at the construction site for concrete construction. The quality of the sand is as important as other materials for concrete. The most different, which passes through the 4.75 mm IS strainer, is known as the fine aggregate.
