Outline of Final Research Achievements |
The strain rate dependent responses of concrete mortar and cement paste cylinders those diameter is 50mm and hights is 100mm were investigated using uniaxial compression tests with high and low loading rates. The influence of pore structure and interfacial transition zone were focused on. Experimental results suggests that developing of capillary pore enhances strain rate effect. It is also suggested that the effect of ITZ is relatively small.
