FINE: Stone dust, a waste product from quarries or stone works, can be added to smooth mixes for smallscale work. It adds strength (?), reduces shrinkage on setting, and may add to the visual appearance of the concrete. Limestone (dolomite) or marble dust (used for swimming pools) are two types of stone dust. EXTREMELY FINE:
