“…Moreover, the addition of EDW and AEFA reduced the clay size fraction of the soils due to flocculation of clay particles through cementation. Therefore, EDW and AEFA treatment made the soil more granular [20,[31][32][33]. Additionally, decreasing PI increased the workability of the soils.…”

Türkiye is surrounded by active faults that have the potential to produce big earthquakes. Recently, one of these faults has become active. Two earthquakes of magnitude 7.7 and 7.6 occurred 9 h apart on 6 February 2023 in Kahramanmaraş. It is reported that 150 million tons of earthquake demolition waste (EDW) is estimated to be produced as a result of those natural hazards. This waste poses a serious risk to both the environment and human health. Its use in geotechnical applications will provide serious environmental benefits. In this study, Afşin–Elbistan fly ash (AEFA) and EDW were used to stabilize weak clayey soils in different proportions. Samples were prepared by separately adding 5, 10, 15, and 20% AEFA and EDW to high-plasticity clay. The AEFA used in this study was used because the production of AEFA is too high, and it is not used in concrete production because it does not comply with the standards and causes serious environmental problems for the region. The Atterberg limit, standard compaction, unconfined compression strength (UCS), triaxial, and California bearing ratio (CBR) tests were performed on soil samples, and samples were prepared from soil mixtures with various proportions of AEFA and EDW added. In addition, clay mixtures were prepared with EDW by keeping the AEFA ratio constant at 15% and their effects were also investigated. According to Atterberg test results, the natural soil class was determined as high-plasticity clay, the soil class of the mixtures created by adding EDW and AEFA was determined as low-plasticity clay, and all ternary mixtures were determined as low-plasticity silt. In addition, the maximum dry density increased for all mixtures, while the optimum water content decreased. A significant increase was observed in UCS test results, especially in ternary mixtures. While cohesion increased in AEFA mixtures, it decreased in ternary mixtures as the EDW ratio increased. It was observed that the internal friction angle increased in all mixtures. According to CBR test results, it was determined that the binary AEFA mixture ratio was 20%, the binary EDW mixture ratio was 10% and above, and all ratios of the ternary AEFA + EDW mixtures could be used as road sub-base material. After the major earthquake disaster, the use of EDW is of great importance for the environment. As a result, AEFA and EDW were found to enhance the geotechnical properties of clay.

“…When soil reinforcement with natural and artificial additives is examined in the literature, it is seen that there are sufficient studies [5]. Among the studies with different reinforcement materials, Diallo and Ünsever [6] determined that the strength of the soil can be increased while construction debris waste and lime were used as reinforcement materials in different percentages. Reinforcement was applied by adding 2% lime and construction debris at rates ranging from 5% to 35% with increasing rates of 5% to the soil.…”

Geotechnical investigations are one of the most crucial part of the constructions in order to save the time and effort spent on the projects. Particularly, in case of the clays with high plasticity are encountered in the analysis of bearing capacity and settlement of structures such as buildings, roads and dams governs the design. The possible solutions can be leaving the land, reaching a strong soil by passing the weak one, removing the weak soil by replacing it with a higher strength material, and applying soil improvement methods. Glass fibers are one of the synthetic additives which may be used to address improving the weak soil properties. In this study, the effect of alkaline resistant glass fiber additive on the undrained shear strength of the clayey soils was investigated. Fibers with distinct lengths were added to the natural soil at the increasing rates and the mixtures were prepared in the optimum water content. The prepared mixtures were compacted in a compaction mold with a diameter of, a diameter of 5 cm and a height of 10 cm with standard energy. A total of 210 cylindrical samples, 10 of natural clay and 200 of fiber reinforced, were tested for unconfined compression test (UC). The maximum increase was at 0.5% of fiber blend of 40 mm length. As a result of 210 UC tests, it was observed that the glass fiber additive with high alkali resistance increased the shear strength of the clay soil.
