Re: Polypropylene Fibers

[Subject Prev][Subject Next][Thread Prev][Thread Next]
We have done it in metal bldg slab-on-grade design, where mesh or bar is being used for tension reinforcement at the rigid frames and poly is used for plastic shrinkage control.
  
Axim Concrete Technoligies makes a similar fibrillated strand called 
Fibrasol F. They're out of Middlebranch, OH.

Has anyone used polypropylene fibers in addition to either steel fibers or
regular reinforcement to help reduce initial plastic shrickage cracks?

If so, what other manufacturer's are out there in addition to Fibermesh?

Thanks,
