    • iv ACKNOWLEDGEMENT
    • v ACKNOWLEDGEMENT First and foremost we thank the almighty, the greatest architect of the universe for giving us such a speculate years. At the outset, we greatly express our profound gratitude to our beloved Correspondent Thiru.R.K.VISHWANATHAN,B.A.,and all trust members for the extensive facilities spared to us. We are greatly indebted to express our deep sense of gratitude to our principal, Prof.S.KUPPUSWAMI, B.E., Msc (Engg). Dr.Ing (France) for his valuable advice and encouragement during the project. We are grateful to thank our beloved Dean of School of Building and Mechanical Sciences Dr.K.KRISHNAMOORTHY, M.E., Ph.D., FIE, FIV for his infallible inspiration and guidance. We take immense pleasure to express our heartfelt thanks to our beloved Head of the Department Prof.S.KRISHNAMOORTHI, M.E., for his encouragement and kind co-operation. This work would not have been materialized without the great guidance given to us by our guide Mrs.S.SUCHITHRA, M.E., who had been a constant source of ideas and inspiration with encouragement. We express our sincere and deep gratitude to our beloved staff member Mrs.J.POORNIMA, M.E., for extending their kind co-operation, moral support and encouragement for completing this project work.

    • vii ABSTRACT
    • viii ABSTRACT This paper outlines the method of preparation, testing procedure and salient results on the eco-friendly concrete that is manufactured using the waste products of steel industries and Manufacturing Sand industries. Steel slag can be used in the construction industry as aggregates in concrete by partial replacing natural aggregates. Natural aggregates are becoming increasingly scarce and their production and shipment is becoming more difficult. Most of the volume of concrete is aggregates. Replacing all or some portion of natural aggregates with steel slag would lead to considerable environmental benefits. The primary aim of this research was to evaluate the mechanical properties of concrete made with steel slag aggregates and steel slag. This Project has shown that partial replacing some percentage of natural aggregates by steel slag aggregates and M-sand. Initially, different natural and manufactured sand M-sand samples to be used in the concrete mixes were collected and their physical properties were studied. The results showed that partial replacing of 5 to 30% of steel slag and M-sand aggregates by volume for natural aggregates. To find the optimum value of partial replacing of steel slag and M-Sand. The compressive strength, Split tensile strength, and Modulus of rupture, Modulus of elasticity of specimens were determined adopting conventional testing procedure. The present study indicates that concrete having very high strength can be produced with the above mention waste products of steel industry and Manufacturing Sand industry.
