Abstract: The economy of a developing country depends to a great extent on the construction industry. Developing countries like India are investing heavily in infrastructure development. The excessive exploitation of natural resources for construction threatens the sustainability of aggregates and poses a number of serious problems. At the same time, the disposal of fly ash and stone residues in landfills cause several environmental crises and pollute the environment. This article deals with a study on the structural behavior of the partial replacement of fine natural aggregates by 0 -40% crystal stones in order to obtain the flow properties of fly-ash-based self-compacting concrete (SCC) by using super plasticizers. Many tests have been done to test the feasibility of using crystal stones in M30 grade SCC. On the basis of the results obtained, the optimum percentage of fine aggregates with crystal stone was calculated at 30% and it was concluded that the increasing percentage of crystal stone replacement by fine aggregates did not affect its workability. The structural performance of simply supported RCC beams of size 150 × 200 × 1500 mm made from SCC with crystalline stone was tested.
