The CDP model doesn't explicitly account for microstructure or long-term properties like creep and shrinkage. To obtain a more realistic simulation, consider manually incorporating porosity data as a material property. However, be aware that this can significantly increase computational time.

Geopolymer concrete differs from ordinary concrete in terms of its chemical composition and behavior, but in many cases, the Concrete Damaged Plasticity (CDP) model in Abaqus can still be used. However, parameters like tensile strength, fracture energy, and plasticity might need adjustment to reflect geopolymer concrete's specific characteristics. Always validate with experimental data. Thank you.

The CDP model in Abaqus can be used for geopolymer concrete, but it requires careful calibration. Geopolymer concrete differs from ordinary concrete in tensile behavior, fracture energy, and ductility, often showing higher tensile strength but lower ductility. Parameters such as dilatancy angle and damage evolution must be adjusted based on experimental data to reflect these differences accurately.
