Beschreibung
The concept of the self-compacting concrete (SCC), was created and developed at the end of the eighties after the development of new organic additives. It has high flowability and moderate viscosity, and no blocking may occur during flow. Several mix design methods for SCC were proposed by Okamura and Ouchi. The interest of those concretes appeared only at the end of the nineties. Self-compacting concrete is a brittle material with a low strain capacity. Reinforcement of self-compacting concrete with short randomly distributed fibers can address some of the concerns related to self-compacting concrete brittleness and poor resistance to crack growth. Fibers, used as reinforcement, can be effective in arresting cracks at both micro and macro-levels. At the micro-level, fibers inhibit the initiation and growth of cracks, and after the micro-cracks coalesce into micro-cracks, fibers provide mechanisms that abate their unstable propagation, provide effective bridging, and impart sources of strength gain, toughness, and ductility.
