A New Method for Measuring the Length of ITZ on Concrete Section by Digital Image Processing Technique

Abstract:

The accurate analysis of the length of the interfacial transition zone (ITZ) between aggregates and the hardened bulk cement paste is of great importance to the definition of the effective diffusion field in concrete. A new method for measuring the length of ITZ on concrete section by digital image processing technique is proposed in this paper. Compared with the traditional method, the ITZ on concrete section can be discriminated and the length of ITZ can be measured by the method presented rapidly and accurately, and the method can be used in various section forms of concrete specimens.
