PB EUROFIBER ANTI SPALLING

Spalling Protection Fibres: How They Work

In the event of a fire, the PP-fibres embedded in the concrete melt, creating a permeable capillary network which permits escape of the gases evolved. Special PP grades with low melt viscosity rates provide enhanced fire resistance as shown by tests conducted with concretes of various types.

The results: Reduced spalling, Upgraded structural safety.

HPR (Heat Prompt Reaction) / High-Performance PP Fibres / Patented Technology

What sets PB EUROFIBER HPR apart from conventional PP anti-spalling fibres is its outstanding flow capability in the molten state.

In the event of fire, this ease of flow permits quick and efficient formation of a permeable capillary network which vents off vapour pressure from the concrete, therefore reducing more efficient spalling.

HPR-Fibres / Advantages over Conventional Spalling Protection Fibres

  • Approx. up to 40 – 50 % lower fibre dosage
  • Lower fibre costs per m3 concrete in most cases
  • Ease of processing
  • Reduced need for concrete additives
    such as flow agents, stabilizers, etc.
  • Increased stability of the concrete
  • Reduced impact on slump behaviour
