“…Consequently, the region is characterized by a large amount of soil with a high-water content. This poses a challenge when using such soil as a construction material in civil engineering, as it must support the weight of the buildings constructed upon it [1][2][3]. Problematic soils beneath foundations often lead to issues such as bearing capacity problems, differential settlement, and unacceptable lateral motions upon loading.…”

Clay soils that tend to have the potential for landslides and earthquake-induced cracking are a serious problem in the development of infrastructure and settlements in the area. This research investigation sample was collected at a quarry in several areas of Aceh Besar District to identify problematic soil behavior in various quarries. The method used was stabilization by conducting compaction testing to obtain the optimum moisture content of the natural soil. The quarry soil samples taken were disturbed samples, which were then tested directly at the Soil Mechanics Laboratory. The data used in this study is the plastic index (PI) value. This research aims to assess stabilization strategies for problematic clay soils as an earthquake risk mitigation effort in the Aceh Besar region. The results of this study are expected to provide practical guidance for stakeholders in planning and developing more earthquake-resistant infrastructure in Aceh Besar. The result of the test showed that the OMC value was 36.3% with a dry weight of 1.22 gr/cm3.

“…Various materials are employed to decrease the disadvantages of soil, like fly ash [ 19 ], urban waste glass powder-based geopolymer [ 20 ], lime-silica fume [ 21 ], graphene oxide [ 22 ], magnesium oxide [ 23 ], and cement [ 24 ]. However, cement production emits around 7% of CO 2 emissions worldwide, contributing to environmental issues like global warming, according to Yu et al [ 25 ].…”

Hydrochloric acid is prevalent in numerous industries; leakage of this acid may cause persistent problems in the soil. The study aims to prevent any adverse impact of acid on the strength characteristics of silty clay soil by modifying the soil’s acid resistance. In this study, unconfined compression tests are performed to investigate the strength of contaminated silty clay soil with concentrations of 4%, 8%, and 12% of HCl solution and the strength of treated soil with 0.4%, 0.5%, 0.6%, and 0.8% of nano-magnesium oxide. In addition, the strength of the soil enhanced with nano-MgO contaminated with different concentrations of hydrochloric acid was investigated to assess the effect of nano-MgO on modifying the acid resistance of clay soil. Moreover, the FE-SEM test was performed to analyze the microstructure of the soil under different circumstances. Based on the results, the strength of clay soil decreased due to contamination with the hydrochloric acid solutions; the reduction in strength was more noticeable when the acid solution became more acidic. Adding 0.6% of nano-magnesium oxide enhances the strength by about 114%. Findings show that adding 0.6% nano-MgO to the soil before exposing it to hydrochloric acid can enhance its acid resistance; the strength of the treated soil with nano-MgO was better at resisting the acid than the untreated soil.

“…In construction, graphene oxide can address the shortcomings of cement-based materials, such as brittleness and high permeability, and enhance mechanical strength up to 120 GPa (Xu, 2018). Moreover, graphene oxide can stabilize silty soil and soft clay for building foundations, making it a promising material for construction projects (Fattah et al, 2021;Mahmood et al, 2021;Yuan et al, 2023) Nevertheless, graphene, like other carbon-based nanomaterials, is water-insoluble, posing challenges for even distribution in cement mixes (Suo et al, 2022;Zhao et al, 2020a). In contrast, graphene oxide (GO), composed of single-layer sp2-hybridized carbon atoms with oxygencontaining groups, exhibits good hydrophilicity and cost-effectiveness, making it a popular choice for concrete mixes (Krystek et al, 2021;Aliyev et al, 2019;Suo et al, 2022).…”

The growing demand for cement production to support the rapid growth of the construction industry has resulted in a significant contribution to global carbon emissions due to the high energy requirements of cement production. Addressing this issue requires the development of eco-friendly cement modifiers/additives. Graphene, known for its exceptional properties, has emerged as a versatile material in various domains, including construction. Its incorporation into cement has exhibited promising prospects, surpassing geopolymer performance and enhancing cement quality. Nevertheless, challenges persist, such as inadequate dispersion in concrete mixtures and quality control issues during large-scale production. Harnessing the potential of graphene oxide can revolutionize cement performance and contribute to a more sustainable construction industry. Addressing dispersion challenges and ensuring successful large-scale production are pivotal steps towards realizing these benefits. This comprehensive review investigates the potential of graphene oxide in the construction sector, specifically focusing on its capacity to reinforce cementitious composites and highlighting the associated implementation challenges, paving the way for more sustainable cement production with a touch of scientific excellence.
