EXPERIMENTAL EVALUATION OF STEEL AND POLYPROPYLENE FIBRE CONCRETE WITH NORMAL CONCRETE

Many researches have been currently going to modify and improved the concrete properties by the addition of different types of materials. This paper represents the Optimum use of the fibres with the normal concrete mixture and will also help in achieving the desired results. This research work explores the effect of fibers i.e. steel and polypropylene with normal concrete. For this purpose, 120 specimens tested for each investigation of their physical properties like compressive strength, flexural strength and split tensile strength respectively. During olden days, only plain concrete were used and after that reinforced of steel concrete was introduced. In this work, the effects of steel and polypropylene fibers were observed after 28 days of casting. For this purpose, we kept the main focus on aspect ratios of fibers, orientation of fibers as well as quantities of fibers. The experimental results show that the hybridization of fibers has slight effect on compressive strength values, while it causes increase in modulus of rupture (flexural strength), toughness (compressive strength) and impact resistance (tensile strength) values. The concrete with fibers reinforcement increased the strengths any all cases. At Some places the polypropylene fibers and somewhere steel fibers. But after observing by T-test techniques and statistical data, it is also showing the all values are beneficial for the grade M40 mix with fibers.
