“…The mechanism of improving the mechanical and durability properties of concrete using nanomaterials is mainly attributed to the nucleation effect, the filling effect, the pozzolanic effect, the bridging effect, and ITZ enhancement [91,92,95,96]. graphene oxide, nano-silica, and nano-aluminium oxide of different proportions in concrete [32,86,97,98]. The growing trend of incorporating SCMs and nanomaterials in concrete to achieve sustainable concrete solutions must be comprehensively assessed with respect to its reactivity, mechanical properties, microstructural properties, and durability [67].…”

“…The results indicated a significant compact microstructure with reduced porosities and fewer cracks around the ITZ area when compared with the control sample, indicating the additional formation of CSH due to pore filling and pozzolanic reactions of the nano-additives. Various studies have been conducted to understand the properties of carbon nanotubes, nano-titanium oxide, graphene oxide, nano-silica, and nano-aluminium oxide of different proportions in concrete [32,86,97,98]. The growing trend of incorporating SCMs and nanomaterials in concrete to achieve sustainable concrete solutions must be comprehensively assessed with respect to its reactivity, mechanical properties, microstructural properties, and durability [67].…”

This review focuses on recent advances in concrete durability using graphene oxide (GO) as a nanomaterial additive, with a goal to fill the gap between concrete technology, chemical interactions, and concrete durability, whilst providing insights for the adaptation of GO as an additive in concrete construction. An overview of concrete durability applications, key durability failure mechanisms of concrete, transportation mechanisms, chemical reactions involved in compromising durability, and the chemical alterations within a concrete system are discussed to understand how they impact the overall durability of concrete. The existing literature on the durability and chemical resistance of GO-reinforced concrete and mortar was reviewed and summarized. The impacts of nano-additives on the durability of concrete and its mechanisms are thoroughly discussed, particularly focusing on GO as the primary nanomaterial and its impact on durability. Finally, research gaps, future recommendations, and challenges related to the durability of mass-scale GO applications are presented.

“…The ProKnow-C method [29] was used to carry out the Systematic Literature Review (SLR). This method is a structured approach for selecting relevant studies, synthesizing evidence, and identifying knowledge gaps, which has been widely used in the literature [30][31][32]. Figure 1 shows the main stages of the SLR on cementitious materials with added OSA.…”

Considering the growing environmental concerns associated with construction industry activities, this article reviews the potential use of oil shale ash (OSA) as a cement substitute in cementitious materials. Specific issues to be investigated include the ideal OSA content to be incorporated into the mix, the optimum oil shale (OS) burning temperature for obtaining the ash, the influence of the specific area and chemical composition of the OSA on the composites, as well as the effects of its addition on the fresh state, mechanical and durability properties. To this end, the ProKnow-C systematic literature review process was adopted for the first time to study this topic, resulting in a portfolio of 14 manuscripts associated with the questions to be analyzed. The primary outcomes include: OSA contents between 10 and 30% are suitable for replacing cement; the ideal burning temperature for OS is between 600 and 800 ºC; high specific areas (between 6000 and 8000 cm2/g) improve pozzolanic activity; high OSA contents may require the use of water-reducing additives to improve workability; incorporating OSA into Portland cement-based materials can improve their compressive strength and durability. These conclusions highlight the importance of understanding the effects of incorporating OSA in developing cementitious materials, providing a basis for future research.

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 methods on this topic. A case study was also conducted in a 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.
