Abstract: For long lasting of natural construction materials including natural sand and aggregate, due importance should be given for sustainable development in the construction field. As it is well known fact that concrete is hugely consumed by the humans for construction activities, making concrete as sustainable material is unavoidable. Although concrete has enough flexibility to use range of materials in its production, understanding performance of concrete with different materials is important for its end use. In the present investigation an effort was made to produce concrete with fine aggregate from construction waste and natural sisal fiber (instead of regular fibers like glass, carbon and polypropylene) and thereby to make concrete as more sustainable and environmentally friendly construction material. Concrete mixes were produced by replacing natural sand with fine construction waste in quantities of 20, 50, 80 and 100 per cent by weight of natural sand and added 1 per cent sisal fiber by weight of cement in all the mixes. The mixes were tested for fresh properties such as slump and strength properties such as compressive strength, split tensile strength and modulus of elasticity. This paper describes behavior of the concretes under the tests performed

Keywords: construction waste, sisal fiber, compressive strength and split tensile strength
