We often get asked how can fibre reinforcing provide a stronger slab than traditional mesh reinforcing?
The tensile strength of reinforcing mesh only comes into effect when it is bridging a macro (or visible) crack in the concrete matrix. On the other hand, short separate fibres provide a discontinuous, three-dimensional reinforcement that picks up and transfers load stress at a micro-crack level.
This means that fibres provide strength and help to control micro-cracks, even before they form. This encourages higher ductility or toughness. Additionally, using fibre provides three-dimensional reinforcement from the top of the slab right through to the bottom, as opposed to a two-dimensional single layer of reinforcement provided by mesh.
Talk to our engineers today to see how you can use fibres to increase the strength and durability of your concrete slab or structure.
