    PVA Fiber RECS 100

    PVA Fibers (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)- 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 monofillament fibers, they are less likely to be visible in 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). Equally true, the small the fiber, the more fibers there are for any given unit of measure, the more likely they 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.

    PVA 100's are favored for their higher strength and ease of workability compared to the 7's and 15's. These are the most visible of the PVA fibers in finished surfaces due to their length. Ideal for use in flowable (SCC) ECC concrete mixes. See recipes in the Catalog of Products and Techniques.

    Dosage rates range depending on application.

    PVA Fibers for use in concrete countertops and other applications


    PVA fibers are ideal as a primary, or secondary, means of reinforcing artisan concrete objects, including concrete contertops, architectural concrete elements, concrete furntiure, and many other applications. To find out when and where to use pva fibers, read this article about using pva fibers in artisan concrete applications.
