Original Abstract

In proposed paper, the attention is paid to investigation of the importance of the interfacial transition zone (ITZ) in selected fine-grained cement-based composites for the global fracture behaviour. The ITZ is a region of cement paste around the aggregate particles which specific features could have significant impact on the final behaviour of cement composites with a crack tip nearby this interface under applied load. A simplified geometry (consisting three phases – matrix, ITZ, and aggregate) is modelled by means of the finite element method with a crack terminating at the matrix–ITZ interface. Numerical studies assuming various ITZ thicknesses and various ITZ elastic moduli taken from generalized self-consistent scheme are performed.
