Partial replacement of fine aggregate and coarse aggregates

The sanitary and stone cutting industry inevitably generates wastes. This study presents the use of quarry dust—a by-product of crushers as replacement of fine aggregate and ceramic waste as a replacement of coarse aggregate. The sources of ceramic waste are obtained from the industrial areas in Raipur. Presently, in ceramics industries the production goes as waste, which is not undergoing the recycle process yet. The potential of recycled ceramic waste as a substitute for coarse aggregates in concrete has been investigated. The recycling of ceramic waste has been done as it was used as aggregate. Concrete mix with 28 days characteristic strength of 20 MPa was prepared using water/cement ratio of 0.4. The study concludes that the 40% replacement of natural sand by quarry dust and 20% replacement of coarse aggregate by ceramic waste reveals higher strength as compared to 0% replacement of natural sand with quarry dust and 20% replacement of aggregate with ceramic waste. The concrete cubes were cast and tested for the destructive test at last which was compression test that to find out the compressive strength of specimens of hardened concrete at 7 days, 14 days and 28 days.
