FLEXURAL BEHAVIOUR OF CONCRETE BEAMS REINFORCED WITH NEW CARBON-FIBRES SYSTEM

This paper presents the results of an experimental study that was carried out to examine the flexural behaviour of concrete beams reinforced with new carbon-fibres system. The system is named Unresin Carbon-fibre Assembly System (UCAS). By UCAS, a set of cables made of unresin continuous carbon fibres (UCCF) is applied to concrete structure as the reinforcement. The merits of UCAS method include economic advantage, lightweight, uncorrosive, high strength, and adaptability to IT era, etc. By this method, cables made of UCCF with a tensile strength of more than 1.4 GPa may be achieved. In addition, a grid system is considered herein to obtain the role of mechanical bonding like on the usual steel reinforcement. In order to verify the capability of this method, three types of concrete beam have been tested under flexural failure test. The results indicated that the concrete beam reinforced with UCAS showed good statically mechanical behaviour and could be a good alternative for reinforcement of concrete structure members.
