PVA Fibre — High-Bond Cementitious Reinforcement
Allzone Trading supplies PVA (polyvinyl alcohol) fibre for cementitious composites where a strong fibre-to-matrix bond is required — repair mortars, thin sections and engineered cementitious composites. PVA fibre bonds chemically to cement rather than relying on mechanical anchorage alone. Fibre length, diameter and dosage are confirmed against supplier technical data and mix design at quotation.

Technical & procurement detail
Why PVA behaves differently+
PVA fibre is hydrophilic and forms a chemical bond with the cement matrix, unlike polypropylene which relies mainly on mechanical anchorage. That strong bond is what allows carefully designed PVA composites to show ductile, multiple-cracking behaviour instead of a single failure crack — but it also means bond strength must be balanced against fibre pull-out in mix design.
Where it is worth the cost+
PVA fibre costs more than polypropylene, so it is specified where performance justifies it: repair mortars that must accommodate movement, thin sections that must resist cracking, and engineered composites designed for ductility. For simple plastic shrinkage crack control, polypropylene micro fibre is usually the economical choice.
Mix design sensitivity+
PVA composites are sensitive to matrix design — binder content, fines, water content, admixtures and fibre geometry all interact. Published ductile behaviour comes from carefully proportioned systems, not from adding fibre to an ordinary mix. Treat any PVA formulation as a mix design to be trialled and tested, not a dosage to be dropped in.
Handling and dispersion+
Even dispersion is essential; clumps become defects. Fibre is added according to the supplier's sequence with sufficient mixing energy and time to disperse without damaging fibre. Water demand rises with fibre content and is corrected with admixture rather than added water.
Specification options+
Working properties are configurable options within this canonical product, not separate products. Depending on the family, that can include grade, viscosity, mix ratio, pot life and demould time, hardness, colour, particle size or fibre length, and pack format. No configuration is presented as stocked or approved until it is confirmed against the supplier's technical data for the exact material offered. Supplier grade names, factory codes and manufacturer brands are not published here.
What to include in your enquiry+
Send the application, the section thickness, the performance you need (crack control, ductility, toughness), your current mix design and monthly volume.
Frequently asked questions
How is PVA fibre different from polypropylene fibre?+
PVA is hydrophilic and bonds chemically to the cement matrix, giving much stronger fibre-matrix bond. Polypropylene relies mainly on mechanical anchorage and costs less.
Does PVA fibre make concrete ductile?+
Ductile multiple-cracking behaviour comes from a carefully designed matrix and fibre system, not from adding fibre to an ordinary mix. Treat it as a mix design to be tested.
Where is PVA fibre worth the extra cost?+
Repair mortars, thin sections and engineered composites where crack control and toughness govern performance. For basic plastic shrinkage control, polypropylene is usually adequate.
How much is added?+
Dosage is a mix-design decision based on fibre geometry and the matrix, confirmed against supplier data and validated by trial.
Does it affect workability?+
Yes, water demand rises with fibre content. Correct with a water reducer rather than added water, which would weaken the matrix.
Are technical documents provided before ordering?+
Yes. The supplier technical data sheet and safety data sheet for the exact grade offered are provided with the quotation, and the working properties in those documents govern — not any general description on this page.
What quantities are quoted?+
Quantities are reviewed per enquiry, from trial quantities through to pallet and full container programmes for production users and distributors.
