Abstract

Compared with ordinary concrete, recycled concrete has multiple weak interface structure, which is the main reason for the low performance of recycled concrete. Based on the construction of the recycled concrete multi interface model, the vivtorinox hardness of three kinds of interface structure of recycled concrete was tested by Micro Vickers Hardness Tester, in order to characterize the microstructure characteristics of recycled concrete interfacial transition zone. The results show that the microhardness and the width of the interface transition zone can be accurately measured and analyzed by Micro Vickers Hardness Teste after the existing models are sliced, pre grinded and polished. It can be seen that the Micro Vickers Hardness Tester provides a scientific and effective research method for the study of recycled concrete interfacial transition zone.
