Original Abstract

The contribution is devoted to the estimation of fracture process zone (FPZ) extent in a finegrained cement-based composite made from hydrated Portland cement. The zone /characterized with reduced mechanical properties) is located in the vicinity of the tensile crack developed in mechanically loaded specimens. In contrast to purely brittle materials where the crack is localized the fracture zone in cementitious material involves larger area dictated by its internal material length.
