| 要旨 | In this study, expansion agent was used to create random cracks. Various fiber percentages were considered in order to assess the influence of fiber volume on the mechanical properties of RC beams with random cracks. From the strain history it was possible to observe that some form of chemical prestress was caused by the expansion agent. Flexure and shear tests on RC beams were carried out. Steel fibers proved to be effective in arresting the cracks and reducing the compressive strain in the rebars due to chemical prestressing. |
