Many contractors have come to realise the advantages of using the Adfil range of polypropylene fibres in extruded concrete. The addition of these fibres today is a widely accepted practice when it comes to completing high quality contracts.
Without the application of fibre reinforcement, fine plastic shrinkage cracks that occur in the surface of the concrete will result in greater penetration by water, petrol, chemical or de-icing salts. This significantly reduces the life span of the extruded sections. The particularly low water cement ratio mixes used in extruded concrete can be subject to surface tearing when the extruder operates on corners and bends. This leads to early and costly deterioration. Often, the machines used are so efficient at compacting the concrete, the entrained air used to provide freeze thaw protection is removed, thus leaving the concrete without the required protection. For projects using micro and macro synthetic fibres as three-dimensional concrete reinforcement, these issues are a thing of the past!
