The rapid development of urbanization has led to an increase in building construction and demolition waste (CDW), resulting in significant environmental and management challenges. Many researchers have dedicated their efforts to exploring sustainable solutions, particularly in geotechnical engineering, where the applications of nanotechnology and CDW have notably gained increasing attention (Liu and Hung, 2023; Liu et al., 2023; Hung et al., 2024). This study aims to investigate the applicability of CDW for soil stabilization and its potential to mitigate environmental issues, focusing on mudstone soil (MS). Prior to testing, CDW undergoes preprocessing to ensure its suitability and effectiveness. Preliminary results indicate that the addition of CDW significantly enhances compressive strength and reduces swelling behavior of MS. This study will further analyze the mechanism of CDW stabilizing soil through  a series of tests including microstructure analysis and find the best solution to improve MS using CDW composite materials.
