Abstract

The chapter delves into the critical need for soil stabilization in infrastructure development, particularly in Vietnam, where extensive construction projects have led to a high demand for backfill materials. It examines various methods of soil stabilization, with a focus on the chemical method using cement and fly ash. The study presents a detailed investigation into the engineering properties of soil treated with 6% cement and varying percentages of fly ash (0, 5, 10, and 15%). Key findings include the optimal combination of 6% cement and 5% fly ash, which significantly enhances the maximum dry unit weight and optimum water content of the soil. The research also highlights the improvements in compressive strength, splitting tensile strength, and California Bearing Ratio (CBR) values, demonstrating the potential of fly ash as a sustainable and effective material in soil stabilization. The chapter concludes with practical implications for road construction, emphasizing the importance of reducing cement use to mitigate environmental impacts and promote sustainable development.
