| 要旨 |
Although an evaluation of micro regions in concrete is highly important, no specific research has ever been mentioned quantitative measures of these regions. Therefore, this study is conducted to evaluate the micro regions from various types of concrete by using the newly developed micro-bending method. In this study, three types of concrete: normal concrete, recycled aggregate concrete and concrete coated with CFRPS, are used to evaluate the strength properties of micro-regions. As a results, it can be concluded that the micro regions in concrete can be successfully evaluated quantitatively by using the newly developed micro-bending method.
