Effect of Partial Replacement of Cement by fly ash and Fine aggregate by marble dust , stone dust on concrete properties

This Paper Presents the experimental study undertaken to investigate the influence of partial substitution of cement(opc) with Fly ash (FA), and partial substitution of fine aggregate by marble dust (MD) and stone dust(SD). Fly ash is a by product of burnt coal from the Thermal power plants , Marble dust is a waste product from marble industries and stone dust is a waste product from crusher plants. Waste disposal is an important issue in the present time and utilization of industrial waste like fly ash, stone dust and marble dust in concrete making studied to investigate the improvement in the properties of concrete and presenting their use as a alternative materials. The experiments were carried out by substituting 25% and 35% of cement by FA and Fine aggregate is replaced up to 40% by MD,SD .
