A Quasi-Real-Time Approach to Investigate the Damage and Fracture Process of Concrete Using X-ray Tomography

In most concrete CT experiment, the detail information of damage and fracture process is achieved by non-real-time approach, and CT method is always regarded as a qualitative method. In our study, a quasi-real-time method is invented using our experiment instruments. Based on the experiment result, the average CT number is used to analyze the damage and fracture process of concrete specimen, and the theory of damage and fracture process is improved. The different characteristic of fracture form of different loading state is investigated both on the macro and micro aspect. This study provides a convenient and fast method to analysis the concrete qualitatively and quantitatively in the engineering practice.
