Shear strength of recycled aggregate concrete to natural aggregate concrete interfaces

摘要

The main goal of this study was to characterize, using the slant shear test, the bond strength of the interface between recycled aggregates concrete (RAC) and natural aggregates concrete (NAC). This can be relevant in the case of new construction, if precast NAC members with cast-in-place RAC parts are adopted, as well as in the case of rehabilitation of existing NAC structures if strengthened using an RAC overlay.
