Investigation on Strength Properties of Concrete by Partial Replacement of Fine Aggregate by Quarry Dust

This works presents the variation in the strength properties of concrete when replacing sand by quarry dust 0 %, 50 %, 75 %, 100 %. M25 grade of concrete were taken for study slump value is reducing for more % replacing quarry dust. The compressive strength of concrete cubes at the age of 7 and 28 days were obtained at room temperature. From test results it was found that the compressive strength got increased for up to 50 % replacement of quarry dust in the place of sand. This result gave a that quarry dust can be utilized partially in concrete mixtures as a good substitute for natural river sand giving higher strength. So, from the results which we have obtained, it is clear that quarry dust can be used as a good substitute the partial replacement of sand in the concrete.
