“…The local environment, mineral structure, particle bonding qualities, particle size, ion exchange capacities, and other variables determine the sensitivity of soil to contaminants [4]. Pollution of sanitary landfill soil [5] and acidic pollutants in groundwater [6] are examples of soil contaminations. However, petroleum hydrocarbons and industrial discharges are the substances most often implicated.…”

Soil contamination produced by improper management of various petroleum and industrial products causes potential risks to the environment and soil engineering properties. Such contamination causes environmental deterioration and adversely affects soil engineering performance, altering almost all geotechnical properties. Several remediation techniques have been proposed to decontaminate the polluted soils. Choosing the best technique depends on both the energy consumption during operation and the treatment efficiency. The lack of a universally appropriate treatment method and the unavoidable expansion of contaminated land have justified the sake of reviewing the behavior of contaminated soils to develop both environmentally and geotechnically suitable soils for construction projects. The present paper reviewed some soil contamination sources’ backgrounds, effects, and remediation methods. Soils influenced by petroleum hydrocarbons and industrial effluents were evaluated. According to the reviewed studies, contaminants are evidenced to have a negative impact on soils' geotechnical characteristics by increasing settlement and swelling, reducing shear strength, and decreasing permeability. The need to restore the engineering characteristics of soils suggest the necessity to use remediation or stabilization technique. The electrochemical method, bioremediation, and stabilizing by additives are revealed to be efficient in improving the engineering properties and performance of contaminated soils.

“…(A. S. A. Al-Gharbawi, Mohammed Y. Fattah 2022). Laboratory research used 10% and 15% plant fly ash to reduce landfill waste decomposition into soil heavy metals; Plant fly ash reduced soil sample specific gravity from 2.7 to 2.4 (Abdulrahman A. Salim, Zainab B. Mohammed 2022). in addition Gypsum soil improved with magnesium oxide and magnesium carbonate (A. S. A. Al-Gharbawi1,a, M. Y.…”

This study investigates the effectiveness of waste ceramic powder and kaolin clay as additives to enhance the properties of gypsum soil, which is characterized by its low bearing capacity and high compressibility. The goal is to determine whether the addition of these additives can improve the qualities of gypsum soil and make it suitable for construction purposes. Vane shear test and consolidation tests were conducted on various combinations of waste ceramic (5%, 10%, and 15%) plus 2% kaolin clay to evaluate the treated soil's performance. The results showed that a synergistic effect was observed when waste ceramic and kaolin clay were combined, particularly at a ratio of 10 % ceramic and 2% kaolin clay. The treated soil exhibited improved characteristics compared to using each additive separately. The study concludes that incorporating a mixture of waste ceramic and kaolin clay can enhance the qualities of gypsum soil, thereby improving the stability and quality of foundations constructed on this type of soil
