| Abstract: | The main results of experimental and theoretical analysis of aggregate-mortar interface transition zone(ITZ) at home and aboard were presented.The mechanical property of interface elements in the FEM model,such as the thickness of the interface,constitutive relationship,random mechanical characteristics,etc.,were discussed.By analysis of test,theoretical and numerical results,it is concluded that more complete scientific experimentation is needed for further study of the mechanical property of ITZ. |
