An Experimental study on Crushed Stone Dust as Fine Aggregate in Cement Concrete

The deficit of natural sand arise the need of alternative materials for replacement of natural sand. This experimental study explores in detail the crushed stone dust which is locally available industrial solid waste material in India as alternative material to natural sand that is being conventionally used as fine aggregate in cement concrete. The nominal mixes were prepared for grades M-20 and M-30 of cement concrete as per Indian Standards codes using natural sand (NS) and replacement of NS sand to crushed stone dust (CSD) in different proportions. In each case proportion the slump cone test, compaction factor test, density test, compressive strength test and Ultra-sonic pulse velocity test were carried out. The results of the study show that, the strength properties of cement concrete using crushed rock sand is higher and homogeneous to the conventional concrete. The study has present that crushed stone dust can be used as readily available solid waste as an alternative to natural sand in cement concrete construction work and it can reduce the cost of material and construction cost and can helpful to mend the environment issues.
