Lets talk about Steel Fibres
Mesh sits in the middle of your concrete slab and is quite cumbersome. What do steel fibres do?
Steel fibres are small in size and are purchased by the kilogram in large numbers. They are often placed into concrete agitator trucks at the batch plant. When placed into the slab, the large numbers of fibres within the concrete then intercept the micro-cracks within the slab, and prevent the propagation of these cracks by controlling the slab's tensile strength. Unlike rebar and welded wire fabric, or sheets of mesh as they are known in Australia, which are usually placed throughout the centre of a concrete slab, steel fibres are dispersed throughout the slab to reinforce isotropically, so there is no weak plane for a crack to follow.
Increases in flexural strength can make it possible to use a thinner slab and eliminate the cumbersome mesh which is usually heavy and 6m x 2.4m in size. Whether it is for lighter duty commercial service or for heavy manufacturing, SFRC slabs are capable of withstanding any load. The only variable is the addition rate of steel fibres which could be as low as 12.5kg/m3 and as high as 100 kg/m3.
