Soil stabilization with eggshell waste is an important aspect of sustainable engineering and environmental management. It offers a cost-effective and environmentally friendly solution for improving the physical and mechanical properties of soils. This study investigates the transformative impact of eggshell as a soil treatment agent on loess soil (EM). Various tests, including Proctor, collapse potential, Atterberg limits, shear strength, and chemistry of the loess were conducted to assess the changes in soil properties with different eggshell content (0, 2, 4, 6, 8 and 10%). The results reveal that eggshell significantly affects soil compaction, stability, plasticity, and shear strength. Notably, the addition of eggshell, especially at 10% content, shows promise in enhancing soil properties, making it a potential candidate for soil stabilization and moisture management applications. However, the complex relationship between eggshell content and soil behavior underscores the need for further research to unlock its full engineering potential and optimize its application in treating loess soil. Overall, soil stabilization with eggshell waste provides a sustainable alternative to traditional stabilizers, contributing to the goal of environmentally friendly and cost-effective solutions in civil engineering.

Volume change of expansive soils is a challenging issue, which affects various engineering structures all over the world. Consequently, we need environmentally-friendly and cost-effective soil stabilizers to address the challenges related to expansive soils. The utilization of natural fibers allows for the reduction in environmental impact since they are renewable and biodegradable raw materials. Moreover, the current article presents an experimental approach to study the effect of natural fibers on the mechanical behavior of expansive soils. Various experimental tests—such as Atterberg limits, standard compaction, direct shear, swelling potential, and swelling pressure—were conducted on control and treated soil samples using different percentages of fibers. The results of measurements of the physico-mechanical properties after reinforcement of the soil with 1%, 5%, and 10% of natural fibers indicate that the mechanical behavior of expansive soils is greatly influenced by the addition of natural fibers. To conclude, 86% reduction was observed in the swelling coefficient of treated soil. Future research can be done to check the durability of the current practice in detail.

“…Most earthquake ground-motion prediction equations (GMPEs), siteclassification studies, seismic hazard assessment, and the construction of seismic micro zonation maps employ the average shear wave velocity of the upper 30 meters of a soil profile (Vs30) as an essential metric [3][4][5][6][7][8][9]. Table 1 shows European and American seismic site categories based on the Vs30 (seismic codes and structural standards) [10][11][12][13].…”

The most frequent parameter used to quantify seismic site response in ground motion models is time-averaged shear wave velocity in the top 30 m of a site (Vs30), used by many engineering design codes and most recently by published empirical-scaling equations to estimate the amplitudes of strong ground motion. The current study explores the potential comparison of the results from the predictive equations and formula recommendations by the international building code. A total of 53 synthetic and real data models with distinct types of vs. profile were used to determine the theoretical dispersion curves and avoid forward and inverse modeling. In the prediction equation, VR36 and VR40 were employed to estimate Vs30. Furthermore, using VR40, based on the 53 different models, shows a good agreement with Vs30. The thickness of the first layer substantially affects the correlation. The findings calculated by the correlation are not in the acceptable zone for layer thicknesses of 10 < H < 20 m and thin layers at shallow depths with lower shear wave velocity.
