Utilization of Dolomite Powder as Partial Replacement to the Cement

In this generation, we observe the rapid urbanization and industrialization which was leading to the increase in the construction of the projects. Several attempts have been therefore made in the building material industry to put to use natural materials to control the total cost of the project. Concrete is the prime material used in any RCC structure. So, in the construction of any structure concrete is main material to be used in completion of structure. Concrete is a mixture of several ingredients but the main ingredients are cement and coarse aggregate. The natural material can also be replaced with cement and coarse aggregate in the concrete i.e. dolomite. Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO₃)₂. Lime mud is present plentifully in dolomite stone. Dolomite sedimentary carbonate rock which has properties like binding and bearing the loads. In this present study it is investigated to find the strength parameters of M30 grade concrete when the concrete materials are replaced with other natural rock materials. In this study the cement and coarse aggregate which are replaced by using natural material i.e., dolomite at various percentages. The specimens are casted by replacing cement with dolomite powder and coarse aggregate with dolomite crushed stone at 0%, 10%, 15%, 20%, 25%, 30%, 35% and 40%. The cubes and cylinders are casted and cured and tested at the age of 7, 14 and 28 days to know the strength characteristics like compressive strength and split tensile strength. The obtained values are compared with M30 grade concrete of conventional mix. KEY WORDS: Dolomite powder, Urbanization, Industrialization, Anhydrous carbonate mineral,
