the effect of complete replacement of sand by stone dust in the cement – sand mortar cubes. Ahmad et. al. (1989) investigated by replacing sand with crusher sand (fine sand i.e. passing through 75µ). They found that the compressive strength of concrete having constant slump decreased linearly with increase in percentage of very fine sand.
