摘要: Fiber addition may lead to a strong modification of cementitious material rheological behavior. First, the existence transition in evolution behavior is shown relatively fiber volume fraction, isotropic state. This occurs at critical fraction between regime which hydrodynamic effects govern and direct mechanical contacts fibers are predominant. Then orientation process induced by casting flow highlighted. The effect yield stress on specially studied. Orientation large amount derived from equation describing single orientation.
