Meso-mechanic-Based Dynamic Behaviors of RCC
Compared with the normal concrete in civil and industrial engineering, the dam concrete such as RCC is a kind of concrete material with low strength, large aggregate, and lean cement. However, due to the limited scale of specimen in laboratory tests, it is difficult to carry out dynamic mechanical tests on fully-graded RCC. With the development of numerical simulation, a series of uniaxial dynamic compressive/tensile mesoscopic mechanics tests are conducted with due consideration of the aggregate gradation and interlayer in RCC. It was found that the existence of coarse aggregate can significantly change the crack propagation, and the larger the aggregate size is, the more obvious the strain rate effect is. On the other hand, the interlayer effect is significant under the quasi-staic loads, but increases gradually as the strain rate increases. moreover, the interlayer effect nearly disappears when the loading rate is high enough.
