Find the optimum percentage of quarry dust that can be replaced for cement. Study the effect of strength properties with the optimum cement replacement with another fine aggregate namely bottom ash. Scope of project work was to Make use of the locally available granite quarry dust as partial replacement of cement.
In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available. This present work is an attempt to use Quarry Dust as partial replacement for Sand in concrete.
Various proportions of quarry dust have also been used as partial replacement of river sand. However, there is a reluctance to use quarry dust as 100 replacement of river sand. Quarry dust can be described as the residue or tailing material after the extraction and processing of rocks and that forms fine particles less than 4.75mm.
