Studies were conducted on the tensile and structural behavior of fiber reinforced cementitious composites (FRC). A model was developed to predict fiber pull-out response. Experiments of fiber pull-out at inclined angles show that the pull-out load and energy increase with the inclining angle but the increases are limited by the strength of the matrix. Fiber bundle pull-out tests reveal that fiber bundles reduce the efficiency of fiber reinforcement. A theoretical model has been developed to relate FRC tensile behavior to the parameters of fiber reinforcement including properties of fibers, matrix, and the fiber/matrix interface. A method of direct tensile test which needs only a simple loading fixture was used to study the tensile behavior of FRC containing various synthetic fibers. The failure mechanisms of these synthetic FRC were studied with optical and scanning electron microscopes. Directions for improvement in properties and cost/effectiveness of each FRC were indicated.
