We know construction activities demand a significant amount of natural materials in order to produce cement and aggregate. Procurement of these natural materials significantly modifies the natural sources and creates major environmental problems. . Furthermore, sustainable waste management is another major issue faced by countries all over the world. In order to minimize the environmental impact and energy consistency of concrete used for construction facilities, reuse of construction and demolition wastes can be a beneficial way which leads to sustainable engineering approaches to concrete mix design. The recycled concrete aggregate have some properties like the natural aggregates but the strength is less than the natural aggregates. So the strength of concrete made, recycled concrete aggregates is enhanced by addition of some additives. In this study steel fibres are added in concrete with recycled concrete to increase the workability of the concrete at same water cement ratio, in addition to increase in compressive, tensile & flexural strength of the concrete. Keywords:- Recycle Concrete Aggregate, Steel Fibre, Compressive Strength, Split Tensile Strength, Flexural Strength.
