A sand equivalent (SE) test (BS EN 933-8:1999 on the 0/2 mm fraction) was also used, which evaluates the proportion of very fine and clay sized particles in the whole sample. Manufactured and crushed sands will usually have lower SE values than clean natural sands due to the dust of fracture created during the crushing process.
