The "fiber mesh" is actually loose, chopped, synthetic fibers, about 3/4 inch long.
In the case of my shop floor, they used one bag per cubic yard of concrete and I was told that each bag has about one million pieces of fiber in it.
When the concrete mix is being put in the truck, the bags are thrown in, bag and all. During the mixing process the fibers (and the bag itself) get dispersed throughout the mix and are overlapping at many different angles, thus forming a mesh that helps prevent shrinkage cracks.
Having the mesh added to the concrete did not add much cost the job, but it certainly added to the finished product.
