| 英文摘要 | This research focuses on creating an alternative material to Coral Gravel Limestone (CGL) for model experiments, aiming to reduce damages to marine ecosystems. High-strength, fast-setting gypsum serves as the structural framework, while low-strength clay ceramsite is utilized as a lightweight filler. The strength contrast between these components is employed to replicate the large-diameter pores characteristic of CGL. To enhance the material's adjustability, a sensitivity analysis was performed on four key factors: gypsum water-to-binder ratio, binder-to-aggregate ratio, aggregate particle size, and foaming agent content. An orthogonal experimental design guided this analysis, resulting in regression equations to predict material properties. The optimized mix ratio ( Mclay ceramsite: Mgypsum: Mwater: Mfoaming agent) was determined as 7:42:12:0.12, with a 2 mm ceramsites particle size. This composition successfully emulates the physical and mechanical properties of CGL sourced from a reef in the South China Sea, yielding dry UCS and porosity deviations of 2.6 % and 7.2 %, respectively. Furthermore, CT scans confirmed that the microporous structures of both materials are comparable, establishing a robust foundation for reef engineering model studies. |
