Abstract
Many non-metallic structural materials, such as Portland cement concrete, are limited in their utility b} their low tensile strength and fracture toughness. Toughening agents lend these materials greater flaw tolerance and the ability to sustain greater loads. The operative toughening mechanisms are not understood well in cement-based composites, but are believed to arise from fracture process zones ahead of the crack tip and in the wake of the crack, and act to reduce the stress intensity or shield the crack from the applied loading.
