Fiber Increases Concrete Strength

Using fiber in ready mix concrete is a excellent way of improving the strength of the concrete and to reduce shrinkage cracks.

Crown Hill Ready Mix offers its UltraFiber 500 a cellulose fiber reinforcement for industrial, commercial, residential, architectural, and decorative applications. UltraFiber’s millions of microfibers bond with the concrete matrix to provide unsurpassed crack control with increased durability, impact, shatter , and freeze/thaw resistance. UltraFiber 500 will not ball or fuzz. It is invisible in the concrete and the only fiber that accepts color. This makes UltraFiber the best finishing fiber and the only fiber for decorative concrete. Our fully computer controlled automatic dispenser adds the precise amount of fiber to the mix as required by your job specification.
