Description

Self-compacting concrete for use over profiled steel/ composite metal decking systems. Available either as a plain self-compacting concrete in applications incorporating conventional reinforcement, or alternatively a specially formulated mix containing high-performance steel and micro polypropylene fibres as a replacement for crack-control mesh.

Features and benefits:

  • Highly fluid, and therefore consolidates easily around the deck profile.
  • Rapid and flexible - easy installation allows large surface to be poured quickly.
  • No vibration or power float finishing required.
  • High quality surface finish.
  • Reduced labour requirements.
  • 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.
  • Good pumping characteristics allow high level floors to be poured.
  • No additional propping of the deck is required.
