Dolomite powder, Crushed sea shell, physical, mechanical and Durability properties.



Concrete is most adaptable, durable and reliable construction material over the world and it is the most important basic material in all civil engineering structures. The ingredients of concrete are cement, fine, coarse aggregates and water, which are mixed in a particular proportion to get required strength. Increase in demand of cement around the globe seeks high intention in finding some alternatives to cement in concrete. The inception of new alternative limits the CO2, a major greenhouse effect causing gas.Research is taking place on all corners of the globe in search of different material options. River sand is collected from river beds to build houses and giant infrastructure to satisfy population growth requirements. The emergence of globalization and advanced technology required to meet the requirements of the worldwide economy at domestically and internationally has become a significant issue in preserving the river sand used as a fine aggregate in concrete manufacturing. In this study a small trial is done to modify the properties of concrete by partial replacement of cement with dolomite powder varying from 0% to 10% with interval of 2.5% and fine aggregate with crushed sea shell powder about 20% as constant. Different tests are done to determine mechanical (Compressive and tensile) and durability properties of concrete.
