Abstract:

In recent years, high-performance lightweight cement-based materials (HPLCM) have received extensive attention in the field of foundation treatment in order to meet the comprehensive demands for load reduction, high efficiency and durability in engineering construction under weak and complex foundation conditions. By optimizing the design of binder system and pore structures, this kind of material has achieved high mechanical properties and has good engineering adaptability, while significantly reducing the material density. A comprehensive review is on the composition design principle of HPLCM, its physical and mechanical properties, and its typical application forms in roadbed load reduction, ground reinforcement, void filling and composite foundations. The focus is on analyzing its engineering application effects and the existing technical problems. The future research and engineering promotion directions are expected, which provides the references for the relative engineering practices and scientific research.
