Objectives: Hybrid Fibre Concrete (HyFRC) which make use of Polyethylene Terephthalate (PET) and Steel Fibre (SF) is considered in this research. HyFRC mechanical properties such as splitting tensile strength, compressive strength and flexural strength will be studied. Methods/Findings: By using IS 10262-2009 code, M40 grade HyFRC was designed with steel and PET fibre were included upto 0.5% by volume of concrete. Experimental investigation showed that superior performance was achieved in HyFRC when using the hybrid fibre form instead of single fibre concretes. This investigation concluded that concrete containing PET fibres of 0.12% and steel fibres of 0.38% grouping as the best combination to be engaged in HyFRC for mechanical properties such as splitting tensile strength, compressive strength and flexural strength. Application/Improvements: Optimum proportion of fibres in HyFRC was identified from the mechanical properties results. Thus the crack pattern and ductility behaviour will be studied by using beam column specimens.
