INVESTIGATING MECHANICAL PROPERTIES OF ENSET FIBRE-REINFORCED CONCRETE
This paper presents false banana fibre reinforced concrete. Fibre of false banana was used in concrete mix to improve the mechanical properties of plain concrete. Fibre of false banana (enset) is low cost local available material, which is degradable and environmental friendly and has good tensile strength. It has improved the load carrying behaviour of the concrete. False banana (Ensete- Vetricosum) is a domestic plant in central, southern and south-western parts of Ethiopia, which cultivated by many farmers for different purposes. Farmers use its fibres for sacks, bags, ropes, mats, construction materials, and cloths. There are five tests did in this paper, compressive strength, splitting tensile, flexural and confined strength of fibre reinforced concrete. The main aim of this paper is checking loadcarrying behaviour of concrete due to the addition of fibre. Compared to other building materials, concrete has relatively low tensile strength, ductility, strength-to-weight ratio and susceptible to cracking. The compressive, tensile, and flexural strength of concrete were increased due to addition of fibres of false banana (enset) into the mix of concrete. After the initiation of first crack fibres inside the concrete prevent the increase of crack width and closely space cracks were produced, that helped the concrete to carry some additional loads. The ultimate compressive strength of concrete which confined with fibre rope and unconfined concrete were relatively the same, but confined concrete has resisted additional load by decreasing way after ultimate load reached. After the initiation of cracks, concrete outside of theconfining rope fractured and fall off. However, the core concrete was confined from falling had carried additional compression loads in a decreasing way. Fibre rope reinforced concrete beam was tested in flexural strength testing machine, and ultimate flexural loads were recorded. After cracks were formed, fibre ropes were supported the tensile force have developed in the beam. Addition of fibres reduces the workability of concrete and extra water was added, and hence compressive strength was decreased. In fibre reinforced concrete, additional cement was needed to have good mix.
