Abstract:

Recycled aggregates made of building demolition waste containing concrete and bricks are called recycled brick-concrete aggregates (RBCA). This research experimentally and analytically studies the bond behavior between rebar and RBCA concrete through tests on twenty-two four-point supported beams made of RBCA. The experimental parameters are the replacement ratio of recycled brick aggregates (RBA), concrete strength, stirrup ratio, thickness of concrete shell, diameter of rebar, and anchorage length. The test results indicated that the replacement ratio of RBA had little, if any, influence on the bond failure mode of the specimens, while the bond strength tended to increase slightly along with the replacement ratio of RBA. The normalized bond strength of the specimens with 25 % and 50 % RBA replacement ratio increased by 7.7 % and 11.6 %. As the concrete strength, stirrup ratio, and thickness of concrete shell increased, the normalized bond strength of the rebars embedded in RBCA concrete increased. On other hand, the bond strength decreased as the anchorage length increased. The rebar embedded in RBCA concrete could exhibit as good bond behavior as that in recycled concrete aggregate (RCA) concrete, and fully developed its strength. Based on the test results, a bond-slip model is proposed for the rebar embedded in RBCA concrete. The proposed model taken account of the researched parameters is of practical significance for evaluating the bond behavior of rebar embedded in RBCA concrete components under composite stress. Good agreement is observed between the measured results and the calculated ones, implying sound accuracy of the proposed model. © 2024 Elsevier Ltd
