| Abstract: |
| A new test technology for evaluating the anticracking performance of concrete material under constraint conditions is presented in this paper.This technology can help evaluate the effects of fiber and other factors on the anti-cracking performance of concrete material with the method of stress risers.It is possible to evaluate the anti-cracking performance of different concrete material quickly in the construction site. |
| Key words: concrete,crack,stress riser,slab test method |
