Testing of Fibre Reinforced Concrete Structures: Structural Behaviour in the Serviceability and Ultimate Limit States
MetadataShow full item record
This master's thesis contains studies on moment capacity of fibre reinforced concrete in load-bearing structures. The primary focus has been testing of full scale beams with steel fibres, both with and without additional reinforcing bars. The properties of both the fresh and hardened concrete have also been studied and measured in accordance with current standards and regulations.The concrete used in the experiments was self compacting with a fibre content of 80 kg/m3 corresponding to 1 vol-% of the concrete.In addition to laboratory experiments, calculations were performed according to current guidelines for design of fibre reinforced structures to estimate the expected behaviour of the beams.The thesis also includes literature study focusing on the use of fibres in concrete, material composition, moment capacity and crack development of fibre reinforced concrete.
