Abstract:
Glass and polyvinyl alcohol (PVA) fibres were added to study their effect on workability and mechanical properties of self-compacting concrete (SCC). Four mixes; SCC, SCC with glass fibres (SCC-G), SCC with PVA fibres (SCC-P) and SCC with glass and PVA fibres (SCC-GP) were prepared with a water-binder ratio of 0.35. It was observed that the addition of glass and PVA fibres reduced the workability properties and improved the mechanical properties of SCC. Addition of fibres slightly increased the compressive strength and modulus
of elasticity of SCC. Splitting tensile strength and modulus of rupture of SCC were found to be significantly increased after the addition of fibres. Glass fibres were found to be more effective in increasing the mechanical properties of SCC.
