RCTSE501-SAND EQUIVALENT TEST
Introduction
The purpose of the sand equivalent test is to indicate, under standard conditions, the relative proportions of clay-like or plastic fines and dusts in granular material and fine aggregates that pass the 4.75 mm sieve.
A minimum sand equivalent value may be specified to limit the permissible quantity of clay-like fines in an aggregate. The test may also be used for determining changes in the quality of aggregates during production or placement.
