Topflow Macro Fibre Self Compacting Concrete

Tarmac

Self-compacting concrete containing macro-synthetic and micro polypropylene fibre.

0121 787 5001 https://tarmac.com/contact/

Application

For use in all slab type constructions as a cost-effective replacement for crack-control mesh.

The first pass of the dappling bar should be a light pass at approximately one-third of the depth of the concrete. The second should be a ‘drag’ across the surface, which will hold any fibres present underneath the surface. Consult manufacturer for further details of the finishing process.

Description

Self-compacting concrete which has been specifically developed and adjusted to contain a high performance blend of macro-synthetic and micro polypropylene fibre.

Features and benefits:

  • Offers replacement for most types of crack control or top mesh.
  • Suitable for use with either Topflow Horizontal or plain 10 mm Topflow concrete mixes, dependent on project requirements.
  • Eliminates the need to order, store and place steel mesh reinforcement on site.
  • Reduces the risk of plastic settlement and shrinkage cracking.
  • Increases impact, abrasion and shatter resistance of the concrete.
  • Increases residual strength and enhances durability.
  • Has little or no impact on surface finish quality; floor finishes can be applied as normal.
  • Allows for the potential to increase bay sizes and reduce the number of induced joints in the slab.
  • The fibre blend complies with EN 14889-1: 2006.
