Fibermesh reinforcement

[Hilton5]

?? Alot of information that fibermesh reinforcement has tensile strength. This is a small structure and I am trying to incorporate the slab for uplift resistance. The old rule of thumb of 1.5 x the slab depth still apply for fibermesh? Thanks

Are you talking polypropylene fibres? They add little structural strength, unless things have changed. They improve the concrete by regulating the 'bleed water', and improving hydration.

Microfibres are basically only useful before the concrete sets, as dik suggested. Macrofibres add 'some' structural capacity to hardened concrete. Steel fibres adds more structural capacity. Fibremesh seems to produce all three fibre types, so it is a little difficult to give a one line answer about capacity.

Last time I researched fibre reinforcing for concrete slabs, I found that there were beam tests that showed beam capacity (and therefore some tensile capacity), but there were no test results available for direct tension applications.
If you`re looking for uplift resistance the beam analogy may be most applicable. I`d suggest reaching out to a manufacturer for specifics.
