Microsynthetic Fibers

Formulated to address early age cracking problems, Fibermesh^® microsynthetic fibers help prevent the propagation of cracks in the plastic state – precisely when most cracks occur. During the plastic settlement phase, the fibers create a three-dimensional support network that resists the downward pull of gravity, thus keeping aggregates in suspension and promoting uniform bleeding. This fiber network increases the tensile strain capacity of concrete during the plastic shrinkage phase as well. In applications where aesthetics are especially important, you can choose a Fibermesh^® micro product that provides a virtually invisible finish. With so many proven benefits Fibermesh^® remains the world’s most specified concrete reinforcement micro fiber, year after year.

Shotcrete reinforced with Fibermesh^® micro fibers have shown to improve freeze-thaw durability, resistance to impact and abrasion, improved cohesion and less rebound.

Fibermesh^® 150F micro fiber is the optimized balance of the best type of fiber and the number of fibers for resistance to explosive spalling.  Incorporating a relatively small amount of Fibermesh^® 150F fiber provides a 3 dimensional protection system throughout the concrete and ONLY when there is a fire, do they create the correct form of permeability that is required to relieve the steam pressure that is created inside the concrete.
