Abstract:

Toughening mechanisms of cement matrices reinforced with high volume fiber fraction have been experimentally studied by quantitative image analysis and laser holographic interferometry. It has been found that damage localization in cement matrices can be greatly reduced by the use of fibers. Based on fracture mechanism observed, an R-curve approach has been proposed to predict toughening of matrices due to fiber reinforcement.
