Typical Formulations
The fiber is generally used at a 35% level in the manufacture of factory-finished prefabricated products, either by the spray process or using traditional concrete casting methods. It is also used in the 12% range for reinforced renders as a site-applied mix and can also be used to control plastic shrinkage, cracking, microcracking, and bleeding in the sire-cast concrete.
