Abstract:

A portable real-time dynamic loading apparatus with support of medical CT is developed. This loading apparatus consists of loading host machine, actuator and digital monitoring; and the greatest pressure output of 100 kN, frequency of 5 Hz; the apparatus is available to perform the dynamic tension, compression test with impact, triangular ,sine wave. In addition, the CT test is conducted by the one graded concrete sample, in the sine wave compression load condition; under dynamic loading, the crack propagation, coalescence, through the whole process of CT images are obtained. The apparatus laid the foundation for dynamic CT test of brittle materials.

Key words: concrete, CT, real-time loading, apparatus
