Abstract

Fly ash is the waste generated by industries which is responsible for causing environmental as well as health problems due to dumping and disposal. This research describes the accessibility of using the thermal industry waste in concrete production as partial replacement of cement. By formulation of concrete with the use of fly ash as a supplementary cementitious material was tested as an alternative to conventional concrete. The fly ash has been replaced 50% by weight of cement for M30 mix. Concrete mixtures were produced, tested and compared in terms of compressive and with the conventional concrete. These tests were carried out to determine the mechanical properties for the tests for compressive strength at 7 days, 14 days and 28 days taken at room temperature. Quarry dust is used to reduce the demand of natural sand by using quarry waste . By partially replacing the quarry sand with the natural sand, the effect of strength and workability of concrete has been studied. This paper reports the experimental study and investigated the partial replacement of natural sand with quarry dust. It has been found that the partial replacement of quarry dust with natural sand has a significant effect to enhance the compressive strength . Quarry dust has been replaced 40% with the natural sand.Silica fume has major impact on industries. It is an experimental study to determine the nature of silica fume and its impact on the properties of conventional concrete. By partially replacing the cement with silica fume, the strength parameters of concrete have been studied. Silica fume has been replaced by 15% of cement, by weight for cube. By partially replacing cement with Silica fume, investigation has been carried out and its effect on the important parameters of concrete such as strength and workability has been studied. It has been found that partial replacement with silica fume has a significant effect in the compressive strength of cubes. We are investigating the potential of using fly ash, quarry sand and silica fumes its effect on the strength and workability of concrete. Attempts for improving the properties of concrete with respect to strength and durability.
