RFS400 by Nycon 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 RFS400 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.
RFS400 by Nycon are Poly Vinyl Alcohol fibers (PVA) with a denier of 40 for use in creating fiber-reinforced concrete (FRC). These fibers are designed for the purpose of adding flexural strength to concrete and improving impact and abrasion resistance. RFS400 also provides shrinkage and temperature crack control. These PVA fibers bond on a molecular level (hydrogen bonding) within concrete, creating a multi-dimensional network of tensile (240 ksi (1600 MPa) ) and flexural strength.
