Toproc MF replaces the need for steel fabric in concrete and tackles crack control

 

 

What is Toproc MF macro fibre concrete?

Toproc MF macro fibre concrete has high strength because of the macro synthetic fibres throughout the concrete mix.  It is very cohesive with a dense micro structure.  Toproc MF also contains silica fume which reduces the concrete’s permeability.

Toproc MF macro fibre concrete benefits

• Improved crack resistance

• Impact and spalling resistance

• No use of steel mesh means:

• Faster build time

• Early access to concrete site

• Reduced labour costs

• Improved onsite health and safety

• Lower carbon footprint

• High early compressive strength at 24 hours*

• High strength at 28 days*

• Increased durability compared to conventional concrete

• Low permeability

• Resistant to weathering, abrasion and freeze-thaw conditions

• Very low water/cement ratio

* refer to the Toproc MF datasheet (pdf, 83mb) for full technical details.

Toproc MF macrofibre concrete applications

• Heavy industrial floors
• External hard standings
• Commercial and retail flooring
• Strong internal flooring
• Recycling plants flooring

How does Toproc MF tackle crack control?

In traditional concrete, containing steel fabric, crack reduction is reliant on the steel fabric being placed in the correct position otherwise the level of protection is reduced.

Within Toproc MF, the fibres are uniformly distributed throughout the concrete matrix ensuring cracks are restrained from propagating, regardless of where the cracks start. Toproc MF will also improve impact and spalling resistance when compared to conventional concretes offering greater protection to exposed areas such as the joint arris.
