Study on the New Test Technology for Evaluating the Anti-cracking Performance of Concrete Material under Constraint Condition

摘要：

In this paper, one new test method for evaluating the anti-cracking performance of concrete material under constraint conditions, the dumbbell test is developed. The paper also conducted a comparative study with the other two test method of concrete anti-cracking performance (ring method and slab test method) under constraint conditions. The new test can evaluate the effects of different factors on the anti-cracking performance of concrete material with the device of stress riser. The anti-cracking performance of different concrete materials can be evaluated quickly in the construction site.
