Description
| - The interfacial transition zone (ITZ) represents a serious problem when homogenizing elastic properties of cement mortar or concrete. Although many mechanisms contribute to its origin and evolution, only the wall effect will be studied. Commonly accepted thickness of ITZ, as it appears around the aggregates, is in the range from 0 to 50 μm. Cement hydration program CEMHYD3D extended with the percolation filtering will be used for the reconstruction of the ITZ and following hydration. Imposing periodic boundary conditions and using FEM leads to effective homogenized elastic properties of ITZ. Depending on the cement fineness, the reduction of Young's modulus against bulk paste was found up to 40 % while Poisson's ratio remained almost the same for the ITZ thickness of 24 μm. Validation on mortar samples shows that the results are in accordance with experiment.
