High performance concrete with partial replacement of quarry dust and silica fume

In engineering industry, the improvement of existing materials allows for technological advancement and the construction of more reliable structures without over design. High performance concrete a material widely utilized in heavy structural construction is cheap and dependable material that can be studied to reach its optimum performance. When the general performance of concrete is substantially higher than that of normal concrete, such concrete is regarded as high Performance concrete. In this study the compressive strength of HPC with silica fume of 15% replacement by the weight of cement and quarry dust as partial and full replacement of fine aggregate is investigated. Results were found that the silica fume is beneficial to concrete in increasing the compressive strength of concrete and quarry dust replacement further increasing the compressive strength of high performance concrete. A compressive strength of 23% is increased due to inclusion of silica fume and 12.4 % is increases due to the replacement of quarry dust.
