Abstract

Abstract The study is aimed to determine the effect of varying percentage of dosage of steel and polypropylene fibres in fresh concrete properties and find that optimum percentage of steel-polypropylene fibre which can enhance the more compressive strength, flexural strength and also reducing the crack initiation and reduction of shrinkage cracks. The results present that flexural and compressive strength characteristics influenced by steel and polypropylene fibres. Using steel fibres are found to be more effective for the enhancement of flexural strength characteristics and reducing cracks propagation. Two types of steel fibres namely crimped steel fibre and hooked end steel fibre are used separately with polypropylene fibres. The crimped steel fibre is more effective than the hooked end steel fibre. The workability is also affected by the addition of steel fibres. Workability is more affected by the crimped steel fibres than hooked steel fibres. The amounts of fibres in the SPFRC mixes are varied from 0.5–1% of the total volume of concrete. The variation is also carried out in the combination of steel and polypropylene fibres to enhance the properties of SPFRC Mixes. Steel fibre varies from 0.25–0.85% whereas polypropylene fibre varies from 0.15% and 0.25%. After all the tests carried out on the SPFRC samples, it showed the type of steel fibre to be preferred with Optimum Content of Fibre Mix is proposed.
