摘要
Non-destructive test methods for structure analysis of ultra-high performance concrete were applied after 40 cycles of salt-scaling. Salt-scaling test method was performed using 3% NaCl solution. The main aim of the experiment was to find new way to observe structure changes in ultra-high performance concrete products, which could help for scientists better understand deterioration mechanism of concrete after cyclic salt-scaling. Salt-scaling of UHPC were investigated by ultrasonic pulse velocity, dynamic modulus of elasticity and compressive strength methods. Surface defects were visually identified by fluorescence test method. There are a few publications about salt-scaling resistance of UHPC and fewer articles about nondestructive test methods how to evaluate structure of concrete after certain cycles of salt-scaling, however such research in Europe is not done at all.
