RF4000 are 130 denier, mono-filament macro PVA fibers (Polyvinyl Alcohol) for use in creating fiber-reinforced concrete (FRC). The primary benefits of RF4000 are light-weight flexural strength and increased impact and abrasion resistance. These PVA fibers bond on a molecular level (hydrogen bonding) within concrete, creating a multi-dimensional network of it's tensile strength (120 ksi [800 MPa]).

Meets the requirements of ASTM C-1116, Section 4.1.3 and AC-32 at 1.0 lb (0.45 kg) per CY.

RF4000 can be added directly to the mixing system during or after the batching of the ingredients and mixed at high speed for a minimum of five minutes. Additional mixing does not adversely affect the distribution or overall performance of PVA.

The addition of RF4000 at the normal or high dosage rate does not require any mix design or application changes. A water reducer or super-plasticizer is recommended in concrete products where improved workability and finishability are desired. PVA reinforcing fiber acts with a molecular bond in the concrete with a multi-dimensional fiber network. It does not affect curing process chemically.
