本文采用RBSM-Truss网络模型对硫酸盐侵蚀引起的固相转变和膨胀开裂行为进行了评价。该分析是通过结合水化模型，diffusionreaction模型，和裂纹扩展模型，以评估通过裂纹的离子转移的反馈系统的固相转化和由于硫酸盐侵蚀的膨胀开裂行为的影响。结果表明，该模型可以预测水化过程引起的相组成和物性的变化，以及硫酸盐侵蚀引起的固相转变和硫酸根离子分布的变化。结果表明，膨胀裂纹作为硫酸根离子的缓冲层，对硫酸根离子的扩散过程和膨胀开裂行为有一定的影响。
In this paper, the transformation of solid phase and expansion cracking behaviors due to sulfate attack were evaluated by using RBSM-Truss Network Model. This analysis was constructed by combining a hydration model, a diffusionreaction model, and a crack propagation model in order to evaluate the influence of feedback system of ion transfer through cracks on transformation of solid phase and expansion cracking behavior due to sulfate attack. As a result, the proposed model can predict the change in phase assemblage and physical properties due to hydration process and the change in the transformation of solid phase and the distribution of sulfate ion due to sulfate attack. It was found that expansion crack can affect the diffusion process and expansion cracking behavior as the crack behaves as a buffer of sulfate ion.
