Anna University, Chennai, Tamil Nadu, India ------------------------------------------------------------------------------------------------------------------------------ABSTRACT: resistance, etc. cementious materials are generally This project deals with experimentally on study of quite brittle, with relatively low strength and strain nylon fiber concrete using M25 grade. Nylon was the first capacity under tension. Hence a hand-laid steel bar truly synthetic fiber to be commercialized. All nylon absorbs reinforcement is usually necessary to increase tensile moisture depends on temperature, crystalline & humidity. It strength. For low reinforcement levels, the partial or provides secondary reinforcement that is always positioned even complete replacement of this conventional in compliance with building codes. Savings time and money reinforcement by fibers is an advantageous be eliminating the purchase, storage handling, cutting & alternative. Fibers may also be applied to control the placing of wire mesh. Allows concrete to reach its designed detrimental effects of shrinkage. strength and integrity without the used for welded wire .It A significant reduction in crack width and inhibits plastic shrinkage. Compatible with all other crack spacing is possible, especially at early ages. admixtures, surface treatments and finally finishes like regular concrete. In the designed concrete the sand was They possess a high tensile strength and a high admixture with 2%, 4%, 6% of nylon fiber. The mechanical elastic modulus these are available at relatively low properties such as compressive strength, splitting tensile costs. The high modulus, which is much higher than strength, flexural strength were tested for conventional the one of concrete or cement paste prevents the concrete.

It is obvious that the behavior of HFRC 1. INTRODUCTION depends on the orientations, distributions, aspect Fiber reinforced concrete (FRC) is a ratios, geometrical shapes and mechanical properties composite material consisting of cement, sand, coarse of Fibers in concrete mixtures.

In this composite distributions of Fiber affect the properties of FRC material, short discrete fibers are randomly such as toughness, strength, ductility and crack width distributed throughout the concrete mass. The behavioral efficiency of this composite material is far 2.MATERIAL PROPERTIES superior to that of plain concrete and many other MATERIAL USED construction materials of equal cost.
