| This research investigates the mechanical behavior and fracture toughness of Deep Soil Mixing (DSM) materials enhanced with a new generation of eco-friendly cement binder, Novocem, compared to traditional Portland cement. The novelty of this study lies in being among the first to apply Semi-Circular Bending (SCB) tests and Cohesive Zone Modeling (CZM) to field-extracted soilcrete specimens to evaluate fracture resistance under both Mode I and Mixed-Mode loading conditions critical for ground improvement structures subjected to complex stress states. This research promotes the use of sustainable binders to mitigate the environmental impact of the construction industry, where traditional Portland cement accounts for 8% of global CO2 emissions. The main results indicate that while Portland cement specimens (SCB-P) initially sustain a slightly higher peak traction (0.33 MPa), they are limited by inherent brittleness. In contrast, specimens with the sustainable binder (SCB-S) require 59% higher fracture energy (Gf) than SCB-P at notch angles of 0° and 30°, indicating superior resistance to crack initiation. Furthermore, numerical analysis using FRANC2D validated that the sustainable binder achieves a maximum separation capacity of 4.6 mm, exceeding that of SCB-P by over 50%. These findings demonstrate that the sustainable binder provides enhanced ductility and energy dissipation, making it a more robust and environmentally responsible choice for applications requiring resistance to brittle failure. |
