The Mechanical Properties of Hybrid Fibre Reinforced Concrete using Recycled Aggregate

Abstract

This experimental work describes mechanical properties of hybrid fibre reinforced concrete with recycled aggregate. Now a day an interest has been shown in use of recycled aggregate in concrete for replacement of coarse aggregate. In this study, normal coarse aggregate is replaced by 25% recycled aggregate. The hybrid fibre, combination of polypropylene and nylon fibres are added to enhance the strength of concrete at volume fraction 0.5%, 0.75%, 1%, 1.25%, 1.5%. The mechanical properties of concrete represent compressive strength, split tensile strength, flexural strength properties are studied and the bond strength using pullout test are also conducted
