High-flowability concrete has better workability and can be used to improvethe concrete quality cast in the reinforced concrete members. Bond betweenhigh-flowability concrete and reinforcement is also better than that innormal concrete. To achieve high flowability, usually it is necessary toreduce the coarse aggregate content in the concrete. However, this couldresult in inferior ductility and durability of hardened concrete, and largerlong-term volume change (creep and shrinkage) of concrete. It may alsoreduce the contribution of aggregate interlock as far as shear frictionstrength is concerned. It is the aim of this study to investigate the effects ofcoarse aggregate content on shear friction behavior. Tests on shear frictionstrength are needed in this study. A total of thirty-six specimens will bemade and tested. The test variables include the concrete strength, coarseaggregate content, and amount of shear reinforcement.
