bending of the keys and crushing of the concrete in front of the ribs. The bearing forces, which are inclined with respect to the bar axis, can be decomposed into directions parallel and perpendicular to the bar axis. The sum of the parallel components equals the bond force, whereas the radial components induce circumferential tensile stresses in the surrounding concrete, which may result in

The effect of recycled concrete aggregate properties on
Recycled concrete aggregate (RCA), produced by crushing concrete from demolished concrete structures is a potential solution to this problem. By reusing demolished concrete structures, it can potentially reduce coarse aggregate costs, resulting in reduced CO 2 emissions associated with aggregate transportation, and reduced construction debris being placed in landfills.

Physical modelling of reinforced concrete at a 1:40 scale
Concrete spalling (i.e., crushing of the unconfined concrete) occurred only in the HH and HL specimens. The spalling was not visible by naked eye and a magnifying lens was needed. However, no concrete spalling occurred in specimens LH, LL, and LH. This is in contrast with the behavior of full-scale columns, but it can be explained by the lack of axial loading: the specimen loading conditions

Various studies have shown that FRP concrete beams with sufficient shear reinforcement can exhibit failure through crushing of concrete [30,31,32]. None of the beams reinforced with GFRP rebar that were tested in the laboratory have achieved a load-bearing capacity higher than the characteristic capacity calculated using various guidelines without incorporating reducing coefficients.
