This study is focusing on the tensile strength of PYA (polyvinyl alcohol) fiber-reinforced concrete. By designing mix compositions, a high performance composite can be produced with a small amount of short fibers. Concrete is a material which has high compressive strength, but the tensile strength is only about I 0 per cent of the compressive strength. The project includes the study of PYA fiber by doing research through journals and books and laboratory experimental works. For each percentage of PYA fiber (0%, 0.5%, 1.0%, 1.5% and 2.0%), 12 cylindrical specimens with dimension of200 x 100 are made for split tensile test. The specimens are fairly distributed for tests at 3'd day, 7'h day, 28th day and 60'h day. The specimens were subjected to wet curing for hydration process. The polyvinyl alcohol fibers form a strong bond with cementitious matrix due to their hydrophilic nature and geometric characteristics. The experimental results show that formulations containing PYA fibers presented higher tensile strength. The optimum PYA content in achieving the highest tensile strength of the concrete is found to be I% of the cement content. The addition of I% PYA fiber results to the tensile strength enhancement of 27% at 28th day. The workability of the concrete mix decreases with higher PYA fiber content based on research done.
