“…For a concrete structure to be sustainable, it should emerge as a solution with minimal pollution and costs, whilst increasing comfort and safety throughout its designated service life [7]. Furthermore, sustainable concrete structures also use economically feasible green materials that require lower maintenance and have a higher durability [8][9][10]. Hence, sustainability in concrete construction can be successfully achieved by producing durable concrete structures with extended service life [11][12][13][14].…”

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 utilization of nanomaterials within cement, aimed at enhancing its mechanical properties, stands as a highly promising research frontier. Numerous investigations have delved into the integration of aluminum and clay in nano size [18][19][20][21]. When a small quantity of nanoparticles is uniformly distributed throughout a cement paste, hydrated cement compounds precipitate onto the nanoparticles due to their elevated surface energy.…”

The paper investigates the impact of carbon nanotube-based modifiers on the performance characteristics of lightweight foamed concrete (LFC). The method involves saturating quartz sand with a solution containing a catalyst for carbon nanotube (CNT) growth, followed by the subsequent chemical vapor deposition (CVD) synthesis of CNTs. Evaluation of nanomodified sand samples was conducted using SEM and TEM, thermogravimetry, Raman spectroscopy, and XRD. Compression and flexural strength tests of (LFC) specimens indicated that the optimal proportion of nanomodified sand introduced is 1% by weight with a particle size of 0.16 mm. This resulted in a notable 35% increase in compressive strength and an approximately 32% improved in flexural strength. Furthermore, the modified sample with CNT-based sand exhibited a 27% reduction in water absorption. The paper also presents a potential mechanism to explain the impact of carbon nanotube-based modified sand on the evolving structure of (LFC).

“…Among the important characteristics of this material, its density stands out, since it is very light and varies from 12.00 to 80.00 kg/m 3 (Machado et al, 2019;Parra et al, 2019). In addition, it is a material that has gained great popularity in the construction industry (Marques et al, 2019), so today its use in this area is gradually increasing, especially for the production of normal and lightweight concrete (Ioana et al, 2023;Ngassam et al, 2018); including partial replacement of aggregates (Selvakumar et al, 2022); also, to establish lightweight and ultralight concrete (Serelis & Vaitkevicius, 2022;Sldozian et al, 2023); similarly, for the production of lightweight concrete blocks (Carneiro et al, 2020) and even to reduce noise, using lightweight concrete for subfloors (Pacheco et al, 2017).…”

Over the years, the world has tried to increase the recycling of materials, especially those of artificial origin, this in order to produce compounds that are sustainable and sustainable. Among these materials, concrete stands out as a versatile element, to which different external agents can be added; however, since many of them are not compatible with aggregates, cement or water, can cause some alterations in their mechanical performance. Therefore, the present investigation addressed the study of an artificial material called Microporous Ethylene Vinyl Acetate (MEVA), in order to evaluate its influence on the mechanical properties of structural concrete. MEVA additions were used in ranges of 5.00 %, 10.00 %, 15.00 % and 20.00 % with respect to the volume of concrete, to analyze its behavior in the mix, both in physical and mechanical properties. The results show that the workability and unit weight are affected by the increase in MEVA. Despite this, the mechanical performance showed significant increases in the compressive strength of 8.81 %, tensile of 22.86 %, flexion of 24.51 % and modulus of elasticity of 2.12 %, with the addition of 5.00 % of MEVA after 28 days. Nevertheless, at higher doses there is a reduction in said strengths. For these reasons, it is concluded that the incorporation of MEVA at 5.00 % greatly improves the mechanical properties of concrete for structural use, in relation to the theoretical design strength of 21.00 MPa.
