Fiber Orientation and Efficiency of the Reinforced Silicate Matrix

The orientation of the fibers in silicate matrix (cement concrete) is crucial for the final mechanical properties of the composite. The fiber orientation depends on many factors related to the geometry of the fiber, the percentage of reinforcement, the composition of the concrete, the technology of placing and compaction, as well as the configuration of the structural component, respectively type of formworks. The fiber orientation and efficiency are discussed in this work. The presented analysis is of importance because the establishment of prescription technological prerequisites for effective orientation is directly related to the expected fiber efficiency in the composition of the reinforced concrete and mortar.
