| Abstract: | The strength of rolled compacted concrete provides important effect to the safety of rolled compacted concrete. The random aggregate model was used to simulate the structure of rolled compacted concrete. The extension of cracks and the mechanic properties of rolled compacted concrete in split-tension test were simulated using finite method. The process on split-tension of roiled compacted concrete was studied. |
