【 摘 要 】

An experimental study was carried out to discover the shear behavior of reinforced concrete beam (RCB) using fly ash (FA) as cement replacement material. Variation of FA composition that was used as the research variable were 10 %, 20 % and 30 % by cement mass. Each of the variations has two RCB specimens while two RCB specimens used normal concrete (non FA) as control beams. The beam was reinforced only in the longitudinal direction without shear reinforcement. The beam was tested by the static monotonically loading method. The results showed that the shear strength of RCB decreased by increasing the amount of FA.
