Abstract:
Recently, polyvinyl alcohol (PVA) fibers have been developed, which may be considered as the most moisture absorbent and have good bond with the cement matrix among synthetic fibers. These fibers can be available in various lengths and diameters, and are added for crack control of composite concrete. Control of cracking has become essential in order to maintain the integrity, serviceability and aesthetics of concrete structures. The results show that there is a new parameter t o consider-the effective fiber surface area (Set), which appears to be a good indicator of fiber performance in the cracking behavior of concrete.
