Restrained shrinkage cracking in fibre-reinforced cementitious composites

Banthia, N. / Azzabi, M. / Pigeon, M.

Abstract The influence of seven types of fibres on restrained shrinkage cracking in Portland cement pastes and mortars is investigated at various fibre volume fractions. Linear specimens with one-dimensional restraint were subjected to a drying environment soon after casting. Fibres belonging to two major categories-macro (large) and micro (fine)-were investigated. These two categories of fibres were found to result in distinctly different cracking patterns due, in part, to their different reinforcing mechanisms. An attempt is made to relate the observed cracking patterns with the perceptible micromechanical processes. A ‘fibre efficiency factor’ is proposed which appears to be an appropriate basis for grading the fibres.
