Helix as rebar/mesh replacement
I am considering trying out adding Helix (steel fiber) into concrete and do away with rebars.
Any experience with this positive or negative in slab applications and ICF wall applications?
Thanks in advance.

If considering for ICF application, I would consult with the ICF manufacturer to make sure it will meet their structural requirements.
For a slab, I would check with an engineer, but would still use short polyester fiber for plastic shrinkage crack control.
Helix sounds as if it would add tensile strength and crack-resistance to concrete, but I would be concerned about the longevity of such thin steel.

Also, the one function of rebar in a concrete wall that Helix cannot duplicate is the ability to tie the wall to the footing and create a continuity of tensile resistance, or to resist horizontal displacement, uplift and overturning forces.

Thanks. I agree Helix may not be able to replace the rebar's ability to tie the wall to the footing.
Thanks
