The properties of conventional concrete is improved by addition of fiber in it. By addition of these fibers ductility of concrete is enhanced and brittleness of concrete reduced. In this study Polyvinyl alcohol (PVA) fibers are used as a reinforcing material. Polyvinyl alcohol is a high resistance nonreactive material. It will not oxidize when exposed to aggressive whether conditions and having good affinity with cement. Polyvinyl alcohol fibre of size 6 mm added in five proportions of 0%, 0.125%, 0.25%, 0.375% and 0.5%. the workability of concrete decreased by addition of PVA fibers in it. So, the superplasticizers are used to improve the workability. In this study two different plasticizers Conplast SP 430 and Polycarboxylic Ether (PCE) are used and their performance on the workability and strength of concrete was worked out. The main reason for conducting this study is to find out the optimum dosage of PVA fibers, optimum dosage of super plasticizer and suggest which super plasticizer is more suitable for preparation of Polyvinyl alcohol fiber reinforced concrete.
