“…Also considering this bibliography, 16 papers (84%) investigated at least two different CNT contents, and generally, very high concentrations were more difficult to disperse and in some cases generated pores in the cement matrix, worsening the mechanical properties. This fact and also considering the still expensive price of CNTs suggests that further investigations concerning CNT-concrete focus on contents up to 0.10% by weight of cement, which is consistent with the literature [34].

“…However, as concrete is the most consumed material in the world after water [4] and whose production emits large amounts of CO2 into the atmosphere, studies on CNT-concrete must be carried out in further research, especially modifying it by replacing NA with recycled aggregates (RA), such as civil construction demolition waste (CDW) or even rubber waste. As reported by Reis et al [34], the use of CDW in CNT-concrete contributes to the buildings' sustainability, and CNTs addition, in this case, can contribute to the RC structure reaching the required mechanical strength.…”

“…This mainly stems from reduced compressive strength due to the increased porosity of the CDW-concrete [53,54]. In addition, 17 manuscripts (85% of the bibliography) used the pull-out test, which has good acceptance in the scientific community and presents accurate results, which is in accordance with the literature [10].…”

Civil construction is essential for the world economy and the largest generator of construction and demolition waste (CDW), mainly due to a lack of planning, technological control, and restoration execution, among other factors. While efforts are made to minimize this waste generation, one possible application for CDW is its incorporation into Portland cement-based materials as recycled aggregates, in partial or total replacement of natural aggregates. However, for CDW use to be feasible, the structure performance and safety must be assured, and the adherence between concrete and reinforcement bars, in this context, is a fundamental mechanism. With this perspective, this paper aims to investigate the influence of recycled aggregate on steel–concrete bonding. To this end, the SREE (Systematic Review for Engineering and Experiments) method was employed as a novelty, including a methodology quality analysis, to search and analyze relevant scientific articles published in the last ten years. The results revealed that the use of CDW as recycled aggregates in concrete worsens the steel–concrete bonding, and that ribbed steel bar seems to be the best option when employed in RC structures built with CDW-concrete, although the bar diameter and the anchorage length still need further investigations, and that CDW-concrete’s use can significantly contribute to reducing the emission of greenhouse gases and to capturing CO2 from the atmosphere. Therefore, further investigations should focus on the real influence of recycled aggregate type and replacement content, bar diameter, anchorage length, and CDW’s potential to capture CO2.

Considering the various problems caused by infiltration in civil construction, this study aimed to identify the most appropriate waterproofing methods for different types of surfaces. A study was conducted on the mechanisms of water infiltration on surfaces and the waterproofing methods available on the market, focusing on asphalt blankets, in addition to a literature review highlighting state-of-the-art on this topic. A case study was also conducted in residence in Nova Lima, Brazil, analyzing different waterproofing techniques, including their characteristics and stages. Among the conclusions, it is highlighted that the implementation of adequate project, installation, inspection, and maintenance techniques can significantly reduce the waterproofing failure rate and repair costs and that the excellent choice of materials, along with the skill of the labor force in the application, is fundamental to guarantee the adequate performance of these materials in buildings.
