ABSTRACT: <br /> <br /> <br /> <br /> <br /> <br /> <br /> Concrete is construction material constitutes of mixture between cement paste, aggregate and other admixtures, concrete is strong in compression but weak in tension and if becomes brittle or has low ductility with the increase in strength. Hence it is aften used in the form of a composite section with steel providing the tensile resistance. Plain concrete strength and ductility can be increased, one waycould be used is by using fibers in concrete mixture as micro reinforcement. One new innovation develoved by 3M Scotchcast TM in USA is fibers made fron 20percent nylon and 80percent polymers called Polyolefin. Polyolefin fibers have many advantages compore to the other types of fiber e.g. resistance to corrosion attack, more rigity, higher tensile strength and can be easily distributed uniformly in the mixture. <br /> <br /> <br /> <br /> <br /> <br /> <br /> This experiment tries to get information and to study the contribution of polyolefin fibers in the increase of strength and ductility of high performance concrete. This fibers hopefully could be used to minimize the use of steel reinforcement to resist forces acting on concrete. For that matter then three specimen composition are prepared i.c. FRC polyolefin, FRC steel, plain concrete and compored one to another. <br /> <br /> <br /> <br /> <br /> <br /> <br /> From observation and experimental result being done, it concludes that 2percent volume fractions of polyolefin fibers show a significant increase in strength of concrete. For example FRC polyolefin average compressive strength is 69,354 MPa, increase 8,72percent from ordinary plain concrete with compressive strength of 63,793 MPa. Some how volume fraction more than 2percent show decrease in strength. In general, all FRC polyolefin specimens showing ductile failure modes as expected.
