In recent years, geotechnical engineers prefer environmentally friendly and sustainable techniques in order to improve theengineering characteristics of Expansive soil. The major objective of this paper is to study the engineering properties ofExpansive soil with Ceramic Waste Powder (CWP). A series of laboratory tests such as pH and electrical conductivity tests,Unconfined Compression test, Splitting Tensile test, Free swell Index test, Swelling Pressure test, California – Bearing Ratiotest, and Atterberg’s limit test were carried out in order to evaluate the engineering behavior of expansive soil with CWP. Theexperimental test results showed that the CWP significantly improved the engineering characteristics of the soil. CWPinclusion in expansive soil was tested at 0%, 5%, 10%, 15%, 20% and 25%. The maximum compressive strength and tensilestrength were achieved at a 20% inclusion of CWP in the expansive soil. The maximum compressive strength and tensilestrength at optimum CWP content of 20% were 641 kPa and 78 kPa respectively. The reduction of free swell index percentagefrom 2.7% to 0.5% indicated the replacement of swelling particles of expansive soil by non – swelling particles with respectto the inclusion of CWP. Using the Simple Regression Algorithm, Lasso Algorithm, Ridge Algorithm, and Support VectorMachine (SVM) Algorithm, multiple models for predicting CBR of an expanding soil stabilized with Ceramic Waste Powderhave been proposed in this article. Hence, the CWP can be utilized as a soil stabilizing material in field applications.
