Abstract: Sustainable development implies meeting current needs without compromising the ability of future generation to meets their own needs. It also requisites that development be undertaken, in a manner, that planetary resources are sustained by effective utilization, without unnecessary wastage. Cement production emits carbon dioxide gas and hence its partial replacement by GGBS and silica fume reduces them. These materials have cementitious properties. This is significant because the production of one ton of Portland cement results in emission of nearly equivalent amount of Carbon dioxide. The study undertakes the variation of important properties of M40 grade concrete, namely compressive, split tensile and modulus of elasticity with addition of these replacements in varying percentages. These properties determine the mechanical behaviour of concrete in structures. Steel fibres are also added as a fixed percentage to the concrete, as it improves its ductility and toughness and reduces its susceptibility to cracking. Comparison of the variation of properties with and without addition of steel fibres is also made, to bring out the beneficial aspects of its addition.
