Experimental Study on the Strength of Concrete using Quarry Dust and Marble Powder

The present study involves the replacement of the fine aggregate by using the quarry dust and the waste marble dust in the concrete. In this process the natural sand were replaced by artificial sands. The quarry dust and the marble dust were replaced as an fine aggregate in different levels (0%,25%,50% and 100% ) to find the compressive strength and (0%,25%,50% and100%) to find the flexural strength of the concrete. The concrete mix which was made for this concrete was M25 grade of concrete. The specimens were casted for both quarry dust and marble powder at different levels of replacement of fine aggregates. The cubes and the beams were casted at each level of replacement. The cubes were casted and the process of curing was done on 14 days and 28 days. And the specimens were tested to find the compressive strength of the concrete cube. The beams were casted (1mX150mmX180mm) for each levels of replacement of fine aggregate by quarry dust and marble powder. The specimens were cured and then the flexural strength of each beams were tested. Then the values of the both quarry dust and marble powder results were compared with each other. The load deflection curve was done for each specimen. Then finally these results will compared with each other and then suggestions and recommendations will be provided
