Abstract Concrete is a composite building material composed primarily of aggregate, cement and water. Generally Concrete is strong in compression and weak in tension. With increase in population and urbanization, demand of raw materials such as cement and aggregate has increased in the construction industries. Further it has been recognized that waste from construction & demolition sectors are of large volume and this volume is increasing every year. Utilization of demolished waste offers not only the solution of disposal problems but also helps to conserve natural resources for meeting increased demand of aggregates and save energy. This study deals with the fabrication of M20 grade concrete specimens using construction and demolition (C&D) waste as a replacement of natural aggregates. Cement, Fine aggregate, Coarse aggregates and C & D wastes are tested to determine the physical properties. The C & D waste were incrementally added in 0%, 10%, 20%, 30%, 40% and 50% to replace the same amount of aggregates. The main objective of this study is to use the construction and demolition waste in manufacturing of concrete and making the concrete economic without compromising with the strength parameter. The casted concrete specimens are compared conventional mix. In this investigation various properties like workability, compressive strength and split tensile strength test were conducted. Top Keywords C&D Waste, Coarse Aggregate replacement, compressive strength, split tensile strength. Top |
