| 内容記述 | The effects of structural defects on tensile and compressive behavior of 11Å tobermorite have been investigated by means of molecular-dynamics simulations. It is known that calcium-silicatehydrate (C-S-H）determines the strength of cement. Tobermorite is one of the main models used to simulate and study cement-based materials because of its structural similarity with C-S-H. Recently, it has been found that the crystalline tobermorite makes the concrete more chemically stable and mechanically stronger. Since tobermorite can be considered defective in the concrete, in this study, we systematically investigate the tensile and compressive behavior of 11Å tobermorite with defects. The simulations show that the defects reduce maximum stresses of 11Å tobermorite in both tension and compression. It is also clarified that the degree of strength reduction varied greatly depending on the location of the defect and the direction in which the deformation is applied. |
