Abstract

As the demand of concrete structures is more nowadays and to emphasizing the usage of eco-friendly materials in concrete, in this project the cement is partially replaced by marble powder and natural sand is partially replaced by iron ore tailings. The practical examination has been carried out in order to determine the strength characteristics of concrete. Moreover, the effect of replacing various percentages of marble powder and iron ore tailings on the compressive strength, splitting tensile strength (Indirect tensile strength) & flexural strength has been observed and compared with conventional concrete mix of M30. The Marble powder and iron ore tailings (MP 0%: IOT 10%), (MP 0%: IOT 10%),(MP 10%: IOT 10%),(MP 10%: IOT 15%),(MP 15%: IOT 10%),(MP 15%: IOT 15%) has been used as the partially replacement of cement and sand. As per the investigation, better results are at (MP 10%: IOT 15%) for all cubes, cylinders and beams.
