Research on fracture damage characteristics of loess solidified with steel slag, calcium carbide slag and metakaolin

This paper examines the fracture damage characteristics of loess cured by solid wastes. The results demonstrate that the production of substantial amounts of gelling substances, such as calcium-silicate-hydrate (C-S-H) and hydrated-calcium-aluminosilicate (C-A-S-H) in the specimens, enhances the fracture toughness of the loess. Furthermore, it is confirmed that the fracture angle is the primary factor that controls the fracture damage pattern of the specimens. This study reveals the fracture damage characteristics of solidified loess from multiple perspectives, which provides a fundamental theoretical reference for preventing, controlling, and resolving hazards associated with using solid waste materials as road base materials.
