Fiber reinforced cement composites: a review

Cement composites are mainly of three types: cement paste, cement mortar and cement concrete. All of these types have the same deficiencies, such as low tensile strength and limited deformation capacity, and they thus fail at the first crack appearance. Discrete fiber reinforcement provides a solution for this problem at both of these deficient stages; this has been proven by the studies referenced in this paper. There is a huge difference in the working mechanism of fibers in all of these composites. Fibers, whether microfibers or macrofibers, have found difference in use-weightage according to their properties (size, shape, yield strength, etc.) in different composites. Microfibers toughen the cement pastes more, with respect to other composites and do not allow them to shrink, but they are not capable of increasing the post crack deformation capacity. These composites need microfibers also, in order to prevent shrinkage cracks at the initial stage of hydration, because at this stage their tensile strength is low and shrinkage stresses are produced at a higher rate. The present paper highlights the differences in the use of fibers in various composites, as well as their effect at both stages of cracking, i.e. pre-crack and post-crack stage.
