PVA Fiber RECS 100 /454 gr

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.

PVA fibers become viscosity modifiers, quickly changing the viscosity dependent on their size. The smaller the fiber the stiffer the mix will become.

PVA 100 - 13 mm - 100 microns

Instructions

Due to the fine nature of these fibers, and the fact that they disperse into monofilament fibers, they are less likely to be visible infinished surfaces. 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 smaller the fiber, the more fibers there are for any given unit of measure, the more likely they are tochoke mixes at higher dosage rates. Therefore, the PVA 100 are dosed at higher rates in the more flowable mixes than are the PVA 15 and PVA 7.

Dosage

PVA fibers can be dosed up to 2% of the total material weight. Not all size PVA fibers can be dosed at the maximum rate. It is recommended to perform an individual test to witness the limit of fiber for each application.

PVA 100's are favored for their 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. PVA fibers can be used as a primary or secondary means of reinforcing artisan concrete objects, including concrete countertops, architectural concrete elements, concrete furniture, and many other applications.
