Alongside steel fibres, Maccaferri provides polypropylene fibres and cellulose fibres. The addition of these fibres to the concrete enables:
• Increase in the fire resistance
• Reduction of cracking due to plastic shrinkage
• Increase of the durability to freezing-thawing phenomena
This composite material is particularly suitable for the final lining of tunnels due to its capacity to increase the fire resistance, and it may be poured or pumped directly into the formwork.
