Scarcity of resources and the need to reduce the environmental impacts of winning and processing construction materials and products is placing a greater emphasis on resource efficiency within the construction industry. In this study steel burr are used as construction materials which is commonly created after machining operations such as grinding, drilling, milling, engraving or turning etc. These scrap steel can be recycled by using it as a additional admixture in concrete to increasing the strength of the concrete.
In this project we choose that lathe steel burr as additive material for the M30 design concrete mix. First properties of material like cement, fine aggregate, course aggregate and water are identified then the properties of steel burr are identified and it’s added in various percentage like 0%, 3%, 5% and 7% and the mechanical properties of object are identified. The mechanical properties of burr added concrete specimens compared with the conventional concrete specimens. In this work M30 grade of concrete with w/c ratio of 0.45 is used for conventional concrete mix. The strength and durability properties of steel burr concrete are better when compared to the conventional concrete up to a maximum adding of 5% steel burr. The maximum compressive strength is 4% more and split tensile strength is about 14% more than the conventional concrete.
