These monofilament fibers are available in 3 diameter sizes namely 7, 15, and 100. The fiber lengths are 1/4" (PVA7), 5/16" (PVA15), and 1/2" (PVA100). PVA Fibers disperse into monofilament fibers and thus are less likely to be visible in the finished surface. Fiber visibility in relation to each other is in direct proportion to their various diameters (7 is least visible, 100 is most visible).
The smaller the fiber, the more fibers there are for any given unit of measure, and the more likely they are to choke mixes at higher dosage rates. PVA100 fibers are dosed at higher rates in the more flowable mixes than are the PVA15.
PVA 100 fibers are favored for their higher strength and ease of workability compared to PVA7 and PVA15. PVA 100 fibers are the most visible of the PVA fibers in finished surfaces due to their length. Ideal for use in flowable (SCC) ECC concrete mixes. Dosage rates vary depending on application.
