摘要: Strain hardening cementitious composites (SHCC) are a class of cement based materials which show strain behaviour in tension. This is achieved by multiple microcracking, results tightly spaced crack pattern with relatively small widths (50-80μm, general) and high capacity (up to 4-5%). Due their ductile tight widths, SHCCs commonly used for concrete repair applications. However, due the width spacing, moisture uptake capillary suction can take place very fast. could result rapid access deleterious substances, such as chloride ions, resulting corrosion initiation. In this study, X-ray tomography monitoring quantification water SHCC. Specimens were first loaded different levels uniaxial They subsequently subjected test. The performed test was modelled using lattice model.
