An Experimental Study On Strength And Fresh Properties Of Fiber Reinforced Concrete With The Addition Of Sisal Fibers

Abstract

Concrete is a widely used building material, it is prone to quasi-brittle failure due to its high compressive strength but low tensile strength and it has limited capacity to restrict the energy absorption after yielding. It takes a huge amount of natural resources such as cement, coarse and fine aggregate. An alternative material that can be used in limited quantities to replace these natural resources may improve the performance of concrete. Natural fibers have recently generated a lot of interest in the world of building materials. Keeping in view, this study is conducted on the feasibility of adding naturally available fiber named sisal fiber in the concrete to get durability properties as they are efficient in tensile strength and preventing crack growth. The leaves of sisal plants are used to produce sisal fiber, it is mostly employed in applications such as rope manufacturing in the construction and marine industries. This research will be carried out on M30 Grade concrete and sisal fibers are added at a percentage of 0, 0.5, 1, 1.5 and 2% to the weight of cement and the lengths of sisal fiber used are 1, 2 and 3cm. Concrete characteristics in fresh state are determined by conducting the slump cone test to figure out the water-cement ratio. Strength properties are determined by Compressive, Split tensile and flexural strengths after 28 days curing of concrete.
