Using fibers to reinforce other materials is not a new idea. In fact, it has been practiced for thousands of years, with straw mixed into mud bricks and horsehair included in mortar.
In the early years of the 20th century, asbestos fibers were added to concrete. By the 1960s a variety of materials, such as polypropylene, glass, and steel fibers, were used in fiber reinforced concrete
Fiber reinforced concrete is a composite obtained by adding a single type (steel or synthetic) or a blend (steel + synthetic) of fibers to the concrete mix.
WIRAND® steel fibers are used to reinforce the concrete adding mechanical properties that can be used for structural design purpose.
FIBROMAC® synthetic fibers are used as a complement for the concrete to control the effects of moisture and water lost in the first stage (24 to 72 hours) of curing.
Adding fibers to concrete improves mechanical properties:
* Increases toughness
* Increases ductility and flexural resistance
* Gets higher and more stable tensile strength
* Increases shear resistance
And can improve control for the following effects:
* Fire resistance
Fiber reinforced concrete technology is in continuous growth and expansion, and is now included in most relevant concrete codes around the world. The codes refer to the technical considerations to define this material with or without structural responsibility for design purpose, and guide accurate use of the technology.
