The main aim of the experimental investigation is to find the combined influence on strength properties ofconcrete prepared using Silica Fume (SF) and Quarry Dust (QD). Quarry Dust is used as partial replacement of naturalsand and Silica Fume as partial replacement of cement. In the present experimental investigation the fine aggregate(Sand) is partially replaced 30%, 60% and 100% by Quarry Dust and the cement is partially replaced by 5%, 10% and15% of Silica Fume by weight. The combined influence of Quarry Dust and Silica Fume on compressive strength, splittensile strength, flexural strength and modulus of elasticity of M30 grade of concrete is investigated. The test results ofconcrete prepared using the different combinations of Quarry Dust and Silica Fume are compared with that of controlledconcrete. The variation of different strength properties indicates the same trend as that of controlled concrete. Based onthe test results, it can be observed that the concrete prepared with a combination of 60% Quarry Dust and 10% SilicaFume possesses improved strength properties compared to the controlled concrete. The increase in the various strengthcharacteristics of concrete containing Quarry Dust and Silica Fume can be attributed to the effective particle packingand also the availability of additional binder in the presence of Silica Fume.
