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

M. Syam Kumar | M. Nageswara Rao

Abstract: 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.
