Abstract: Cement production leads to CO2 emissions generated during calcinations of CaCO3 and by burning of fuel, is responsible for about 5% of the CO2 emissions in the world. This can be reduced if the pozzolanic materials such as a flyash replacecement within the limits. Now-a-days river sand availability is also reduced and becomes difficult to find due to which there was a need to find an effective alternative. Stone dust, is found as an economic substitute material for river sand as it is a waste material which is obtained from the crusher plants. It can be used to replace river sand partially in concrete. In the present investigation, we have investigated the strength properties of the concrete made with stone dust as partial replacement of fine aggregate in concrete and fly ash as cement. M30 grade mix design is developed using IS design for conventional concrete and replaced mix. Cube specimens (150mm X 150mm) were prepared for both conventional and 30%, 60%, 100% replacement with quarry dust which were further modified by partially replacing cement with 10%, 20%, 30% and 40% of low calcium fly ash. Tests carried on specimens after 3days, 7days, 28days, 56days and 90 days curing to attain its maximum compressive strength. Graphs were drawn and results are compared with the controlled concrete.
