Abstract

This chapter delves into the properties of Cement Deep Mixing (CDM) columns through unconfined compression tests conducted in Ho Chi Minh City. The study focuses on the unconfined compressive strength (q_u), secant modulus at 50% strength (E_50), and unit weight of CDM columns, providing a comprehensive evaluation of their mechanical behavior. Key findings include the variation of q_u and E_50 with depth, the ratio of E_50 to q_u, and the comparison of unit weights between CDM columns and in-situ soil. The study also highlights the construction procedure of CDM columns and the significance of selecting optimal cement content. The results offer valuable geotechnical parameters for the design and analysis of deep excavation projects, making this chapter a crucial resource for professionals in the field.
