A comprehensive study on physico-mechanical properties of non-metallic fibre reinforced SCC blended with metakaolin and alcofine

Abstract This study presents a detailed experimental investigation on the effects incorporating non-metallic fibers in hybrid form self-compacting concrete (SCC). In this regard SCC was prepared with Alccofine and Metakaolin as partial replacement for cement 15% 20% respectively along fibre combinations namely abaca fibres (0.25%, 0.5% & 0.75%), polypropylene (0.5%, 1%, 1.5% 2%) glass 1.5%, 2%). The fresh properties of without were assessed through standard tests such slump flow, J ring V-funnel tests. conventional mechanical compressive strength test, split tensile test flexural performed at 7 28 days. results reveal that highly influenced by alccofine adopted research. Furthermore, combination improved particular mix 1% 0.25% Abaca had shown better behaviour. Microstructure analyses also done to confirm improvement properties. Scanning Electron Microscope images showed less voids presence more hydrated components conveying usage restricted propagation cracks there reducing percentage use metakaolin alcofine helping forming earlier stage leading strength.
