EXPERIMENTAL INVESTIGATION OF PARTIAL REPLACEMENT OF CEMENT BY USING STEEL SLAG

Civil Engineering

This paper aims to study experimentally, the effect of partial replacement of cement by steel slag, on the various strength and miscellaneous properties of concrete, by using a mix design Mortar. The major aim of this research work is to find the ideal percentage of replacement of cement so as to retard the use of deficient natural aggregates. Steel slag is an industrial by-product of steel industry. It carries the disposal problem and creates environmental issues. Cement is replaced by steel slag to study its imp act on concrete in proportions of 0%, 5%, 10% and 15%. Various strength parameters such as compressive strength of all proportion samples are studied. Also, from the obtained results of different sample proportions of steel slag, it will compare to the results of control mix. From the experimental investigations, optimum percentage of replacement of cement by steel slag will worked out. It has been found that some kinds of slag (Industrial steel slag) are very suitable as substitutes for cement, providing properties above those of the reference concrete. A circular economy is a current tenet that must be implemented in the field of construction. That would imply the study of the possibilities of the use of waste generated, for obtaining materials the used in construction as replacements for the raw material used. One of these possibilities is the substitution of the cement by slag, which contributes to the reduction of cement consumption, decreasing CO2 emissions, while solving a waste management problem. In the present paper, different types of concrete made by cement substitution with different type of slags have been studied in order to evaluate the properties of these materials.
