Abstract

ABSTRACT: This paper provides a review on the surface modification of low-surface energy fibers (polypropylene, polyethylene, and nylon) and discusses on the effects of these treatments toward the physical/mechanical properties of cement-based composite materials. These properties include the tensile, flexural, compressive strength and toughness, stress–strain behavior, modulus of elasticity, and workability. The effects of these treatments on the changes in the fiber/cement matrix interfacial properties are also presented. Studies have shown that various surface treatments have been used to improve the efficiency of the low-surface energy synthetic fibers in the cementitious composites. The modifications are on the basis of physical, chemical, and mechanical methods. The main achievements found have been the development of fibers with modified surface to optimize fiber–matrix adhesion. Moreover, the recently developed surface modifications will allow obtaining high-performance cementitious materials reinforced with the synthetic fibers. GRAPHICAL ABSTRACT:
