The moisture transport and drying shrinkage properties of a certain type of Strain-Hardening Cement-Based Composite (SHCC) are investigated. This material is characterized by the usage of short high-modulus polymeric fibers as reinforcement of a cementitious mortar matrix with comparatively small grain sizes. The drying-induced mass loss and length change of circular cylindrical specimens with a radius of 25 mm have been measured. By inverse analysis of the experiments utilizing an evolutionary optimization algorithm, the material-specific transport and drying shrinkage parameters were identified. A sensitivity analysis revealed that the model assumptions concerning the mechanical material behavior, incorporating damage and creep, had only a small influence on the present inverse analysis results. It was also concluded that for the investigated type of material and the chosen geometry, the directly measured steady-state specimen contraction appropriately describes the material-specific drying shrinkage behavior.

研究了某种类型的应变硬化水泥基复合材料（SHCC）的水分输送和干燥收缩性能。这种材料的特点是使用短的高模量聚合物纤维作为水泥砂浆基质的增强材料，具有相对较小的粒度。已经测量了半径为 25 mm 的圆柱形试样的干燥引起的质量损失和长度变化。通过利用进化优化算法对实验进行逆向分析，确定了材料特定的运输和干燥收缩参数。敏感性分析表明，关于机械材料行为的模型假设，包括损伤和蠕变，对目前的逆向分析结果只有很小的影响。
