Abstract

Highlights: The recent advances on the application of synthetic fibers in FRCC are reviewed. Properties of three types of synthetic fibers, namely polypropylene, polyethylene and polyvinyl alcohol are described. Important parameters affecting the influence of synthetic fibers on properties of FRCCs is critically reviewed. Physical and mechanical properties of FRCCs and their variation with key parameters are discussed. Abstract: Owing to their remarkable physical and mechanical properties, the use of polypropylene (PP), polyethylene (PE), and polyvinyl alcohol (PVA) fibers in cementitious composites has received significant attention in recent years. This paper presents an in-depth review of the recent advances on the use of these synthetic fibers in cementitious composites as reinforcement. The fibers are categorized on the basis of their physical and mechanical properties. Throughout the review, the key fiber parameters have been identified and their influence on the physical, mechanical, and durability properties of fiber-reinforced cementitious composites (FRCCs) are discussed. To explain the observations of these properties, microstructure analyses of the composites and fibers are also presented.
