Evaluation of FRC using Steel and PVA Fibers in Concrete

Concrete is the widely used construction materials. The conventional concrete is enhanced by the addition of fibers in it. The brittleness in concrete is reduced and the adequate ductility of concrete is ensured by the addition of fibers in concrete. Fibers used are polyvinyl alcohol and steel fibres in various volume combinations. The main reason for adding fibre to concrete matrix is to find its compressive strength, split tensile strength, and flexural strength. The base polyvinyl alcohol is highly resistant to the majority of aggressive agent and will never oxidize when exposed to the condition which causes the steel to rust. The hybrid fibres of various combinations in polyvinyl alcohol fibre is 0.1%, 0.25%, 0.5% and steel fibre 0.5%, 0.75%, 1.0% are decided to use in concrete mix. The workability of these fibre reinforced concrete mixes will be increased by addition of super plasticizer. It gives good impact strength, ductility, high load bearing capacity after being cracked, high resistance to corrosion. PVA and steel fiber got wide acceptance as a less hazardous and reasonable cost alternative. It is also suitable characteristic for reinforcing cementitious composites.
