| Outline of Final Research Achievements |
In this study, we focus on the compressive stress field of concrete and clarify the relationship between stress strength ratio and durability for concrete. As a result, we clarified that the difference in stress level influences the degree of progression of deterioration, and the pore size distribution differs before and after deterioration. These results suggested that the compressive stress corresponding to the elastic region of concrete may suppress degradation progression. Furthermore, we evaluated the occurrence distribution and deformation of cracks due to the difference in stress level, and modeled the deformation behavior of concrete in compressive stress field. From these results, we were able to obtain basic knowledge for constructing a reasonable "durability check / deterioration prediction system".
