IMPROVEMENT OF GYPSUM SOIL PROPERTIES USING CERAMIC POWDER AND KAOLIN CLAY ADDITIVES
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
