PVA 15 RECS Fiber 1Lb bag (PVA0151) (801293)
PVA Fiber RECS15 (polyvinyl alcohol) are high-performance reinforcement fibers for concrete and mortar. PVA fibers are well-suited for a wide variety of applications because of their superior crack-fighting properties, high modulus of elasticity, excellent tensile and molecular bond strength, and high resistance to alkali, UV, chemicals, fatigue and abrasion. PVA fibers are unique in their ability to create a molecular bond with mortar and concrete that is 300% greater than other fibers. These are monofilament fibers that are available in 3 different deniers (diameter of the fiber) namely 7, 15, and 100. The fiber lengths are 1/4" (PVA7), 5/16" (PVA15), and 1/2" (PVA100). Due to the fine nature of these fibers, and the fact that they disperse into monofilament fibers, they are less likely to be visible in the finished surface. How visible they are 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 the fibers are to choke mixes at higher dosage rates. This is why the PVA100 are dosed at higher rates in the more flowable mixes than are the PVA15.
PVA15 fibers are a good middle ground between PVA7 and PVA100, providing minimal visibilty and good strengths. b>Size: 1Lb bag
