Simulation method for diffusion performance of tricalcium silicate slurry considering internal pores of particles

The invention relates to a simulation method for tricalcium silicate slurry diffusion performance considering particle internal pores, which is characterized in that after the influence of particle internal pore size distribution and particle porosity is considered, an algorithm of a CEMHYD3D model is improved, and a steady-state diffusion process of ions is simulated by combining the improved model with a finite element model. Different from a traditional diffusion simulation method which only considers the defect of solid particles, the method simulates the influence of internal porosity and pore size distribution of different particles on the diffusion performance by introducing internal pores of the particles. 本发明涉及一种考虑颗粒内部孔的硅酸三钙浆体扩散性能的模拟方法，在考虑颗粒内部孔径分布和颗粒孔隙率的影响后，对CEMHYD3D模型的算法进行了改进，通过将改进后的模型与有限元模型相结合，模拟离子的稳态扩散过程。该方法区别于传统扩散模拟方法仅考虑实心颗粒的不足，通过引入了颗粒内部孔，模拟出不同颗粒内部孔隙率和孔径分布对扩散性能的影响。
