MIXING EFFECT OF DIFFERENT SIZES OF SYNTHETIC FIBERS ON CONCRETE

Polyvinyl alcohol (PVA) fibers have been developed that are highly moisture absorbent and also have a good bond with the cement matrix among synthetic fibers. These fibers are available in various lengths and diameters, and are added for crack control of composite concrete. This paper discusses experimental results of different sizes in surface area of PVA fibers on the splitting-tensile and compressive strengths, drying shrinkage strain, and cracking control from restrained shrinkage and cyclic loading. A parameter is introduced and considered, the effective fiber surface area, which seems to be a good indicator of fiber performance in the cracking behavior of concrete.
