【 摘 要 】

In the present study the effect of using hybrid microfiber reinforcement on the mechanical properties of concrete is studied. Concrete is an important construction material which has low tensile strength and flexural strength. It is proved that addition of fibers improve different properties of concrete like tensile strength and ductility. Improvement in performance by the use of more than one fibre in same concrete is studied here. Hooked steel fibers and glass microfibers (6mm and 12 mm) are used in this experimental study. Influence of each fibre and their combined effect is studied. Fibre is added by volume fraction and it is fixed as 0.5% of the total volume. Mechanical properties are tested by Indian standard methods. From the results it is found that the properties are improved by the use of hybrid fibre reinforcement in concrete.
