摘要 使用 3D 数值工具 MuMoCC 平台对浸出砂浆的长期行为进行了模拟，并成功预测了其机械和扩散特性。水合物（例如氢钙石（CH）和水合（磺基）铝酸盐）溶解的影响被量化，表明它们对弹性模量和抗压强度的降低以及延展性和扩散率的增加具有显着影响。此外，还预测了整个浸出样品的压缩应力-应变曲线和有效扩散系数根据浸出持续时间或浸出深度的演变。
ABSTRACT The long term behaviour of a mortar submitted to leaching is simulated and both its mechanical and diffusion properties successfully predicted using the 3D numerical tool, MuMoCC platform. The effect of the dissolution of the hydrates such as Portlandite (CH) and Hydrated (sulfo-) aluminates is quantified, showing their significant influence on the decrease of the elastic modulus and the compressive strength, and on the increase of ductility and diffusivity. Moreover, the evolution of both compressive stress-strain curve and effective diffusion coefficient according to leaching duration or leaching depth are predicted for a whole leached sample.
