EXPERIMENTAL INVESTIGATION OF CONCRETE COMPOSITE USING NYLON FIBRE

Nylon fiber is not an absolutely new material, it is successfully applied in such fields as mostly found in garment interlinings, tooth brush, Fishing lines, Nets and building structures. At the present time very prospective directions of using nylon fiber is fiber - concrete and fiber - cement, reinforced with nylon fibers, using nylon fiber as post - tension or pretension r einforcing bars in reinforced concrete structures, applying polymeric and metal composites for structures. The main reason that nylon fiber is considered as construction material so rarely in India is non - availability and its high price on shipping, but th e general trend of increasing product of nylon fiber and reducing its cost can said might change this situation in the construction industry. The effects of adding nylon fiber into the concrete matrix on compressive strength of cubes and split tensile stre ngth of cylinders were evaluated in this work. Four test groups were constituted with the Nylon fiber percentages of 0.00%, 1%, 2% and 3%. The results showed the effect of Nylon fiber on concrete has a considerable amount of increase in compressive and spl it tensile characteristics; make a comparison of materials and about reasonability of applying nylon fiber in terms of operating conditions and economics.
