Reinforcing Concrete by Adding Fibers - The Concrete Network

Fibers can be added to the mix in lieu of welded wire mesh. The problem with welded wire mesh is that it often ends up on the ground from being stepped on as the is being placed (particularly if no support blocks are used). Another problem is that mesh does not prevent or minimize cracking-it simply holds cracks that have already occurred together.
