“…3 In order to meet the requirements of structural applications using RAC, plenty of research results about material properties of RAC have been made available in recent years. [4][5][6][7] These results indicated that the amount of recycled aggregates utilised had remarkable influence on the compressive strength of concrete. However, it had only a minor influence on the bond strength when the deformed rebar was applied.…”

“…As shown in Figure 2, demolition and landfilling strategy, if adopted, not only does not preserve the embodied carbon invested to convert the material into an integrated structure but also results in additional carbon emissions during the demolition of the building and the transportation of debris to remote landfills [20]. The recycling strategy is, on the other hand, one of the oldest sustainable strategies to deal with construction and demolition waste [81][82][83][84][85][86][87][88]. Concrete recycling has been highlighted as an effective strategy to reduce carbon emissions and costs incurred in transporting and dumping of debris at remote landfills, reducing the need for the landfill space and providing a sustainable source of alternative aggregate [75,88,89].…”

Building and construction is responsible for up to 30% of annual global greenhouse gas (GHG) emissions, commonly reported in carbon equivalent unit. Carbon emissions are incurred in all stages of a building's life cycle and are generally categorised into operating carbon and embodied carbon, each making varying contributions to the life cycle carbon depending on the building's characteristics. With recent advances in reducing the operating carbon of buildings, the available literature indicates a clear shift in attention towards investigating strategies to minimize embodied carbon. However, minimizing the embodied carbon of buildings is challenging and requires evaluating the effects of embodied carbon reduction strategies on the emissions incurred in different life cycle phases, as well as the operating carbon of the building. In this paper, the available literature on strategies for reducing the embodied carbon of buildings, as well as methods for estimating the embodied carbon of buildings, is reviewed and the strengths and weaknesses of each method are highlighted.

Abstract. We present an effective three-dimensional tool for modeling the influence on the structural behavior of the mechanical behavior of the interface between steel bars and FRP plates glued to concrete beams. The proposed tool reproduces the pull out of the bars and the detachment of the FRP plates. Both opening and sliding of the interface between reinforcements and beam are accounted for. The tool is based on the regularized extended finite element method (XFEM) developed by the authors: the discontinuities are regularized and a mechanically consistent variational formulation is adopted. The considered cases range from the simulation of pull-out tests of steel rebars, to the simulation of single-lap tests in shear and three point bending tests in FRP-reinforced concrete beams.
