Slow stable crack growth is a prominent feature of the fracture behaviour of fibre reinforced cement. The main mechanism for resistance crack growth during crack extension in this type of composite is microcracking ahead of the crack tip. This phenomenon is characteristic of a cement matrix, containing many pre-existing defects which will propagate during loading. Its effects can be calculated by applying linear elastic fracture mechanics to the microcracks. Fibres stabilise the crack propagation as long as they bridge the crack. A statistical study, based on fibre bundle behaviour, allows an explaination of the effect of fibre properties on crack growth resistance in this type of composite.
