Fibers are generally added to concrete as a resistance to cracking and it causes strengthening of concrete. In this project, various tests are carried out on steel fiber reinforced concrete with the addition of different percentages of marble dust to check the influence of fibers on compressive strength of concrete and the optimum amount of marble dust that can safely replace the cement content in concrete. According to various research papers, it has been found that steel fibers give the maximum compressive strength in comparison to glass and polypropylene fibers. An experimental investigation was carried out on the behavior of concrete specimens reinforced with steel fibers and subjected to compressive loading is presented. Tests were conducted on specimens with four different fiber volume fractions. It was observed that Steel fibre reinforced concrete specimens showed enhanced properties compared to that of normal specimens. The present study aims at, developing pavement quality concrete mixtures incorporating marble dust as partial replacement of cement and the use of steel fibres for strengthening of concrete. In this study, the compressive strength for pavement quality concrete mixtures for different percentage of steel fibres and replacement of cement with marble dust are reported. It is found that the maximum increase in compressive strength is for 1% Steel fibre. The savings in the cement can be achieved by replacing some amount of it with the cheaper material like marble dust and the strength decreased is compensated by adding steel fibres. Hence the replacement of cement by marble dust is more economical and the compressive strength is increased by addition of steel fibres.
