A higher sand equivalent value indicates cleaner fine aggregate (i.e. lower clay particles). However, results obtained by Gaynor [25] on 130 samples indicated that there was little correlation between the minus 75 μm material content in a sample and the value of sand equivalent test. Others reported the existence of some correlation between the sand …
