This document provides a bonafide certificate for a project report on the study of mechanical properties of eco-friendly economic concrete. It certifies that the project was conducted by three students, M.Vineeth, Y.Boopathi, and P.Murali, in partial fulfillment of their Bachelor of Engineering degree from Kongu Engineering College. The project investigated replacing natural aggregates with steel slag aggregates and M-sand to produce more sustainable concrete. Tests were conducted to determine the compressive strength, split tensile strength, modulus of rupture, and modulus of elasticity of concrete mixes with varying replacement levels.

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.
