Fiber reinforced concrete which is shortly termed as FRC is a type of concrete which is being strengthened by imparting shreds of some materials onto the soggy concrete mix. Since the concrete is extremely at compressive strength and little median in ductile strength, it might probably break under so many conditions.
A minor break or crack will result in major damages and this is why the fiber reinforced concrete is used. They will likely reduce the chance of being damaged when compared to the usual concretes. The use of fiber reinforced concrete is not a new idea, since it is being used since thousand years until now. In the early 20th century, concrete mix is made with the blend of asbestos fibers and in the later 1960’s a different range of materials including glasses, steel fibers, polypropylene is used.
As per the latest research, reports say that the use of micro fiber reinforced concrete than the usual long fibers ensures improved tensile strength, and moreover it creates additional resistance too. The use of polypropylene reinforced concrete will condense the damages caused from freeze-thaw cycles and also it contracts the chances of explosion in case of fire. Besides this, cellulose reinforced concrete has also shown proven results keeping up its promises. The use of glass fiber reinforcement is exceptionally resistant against the natural environmental conditions. Being an environmental friendly fiber reinforced concrete, they are made out from instinctual natural elements and also take less energy too.
In general, the fiber reinforced concrete is most usually used in making the ground level including the floors and pavement roadway. Also, this type of reinforced concrete could be utilized in making pillars, foundations, raising the beams and many more. The process becomes even powerful when it is made with a combination of traditional reinforcement such as steel mesh and rebar. A latest report has informed that the fiber reinforced concrete is being used in making the ECC, which is called as Engineered Cement Composites! When detailing in particular, the composite is ultimately flexible due to the best mix of fiber and the other materials added in making the concrete.
Fiber reinforced concrete can do wonders and also they enhance the strength of the mechanical properties as follows:
- Makes it rigid and tough
- Improves flexural resistance and ductility
- Improved level of tensile strength
- Improved shear resistance
Besides the above defined positive advantages, the fiber reinforced concrete will improve the overall effects such as strength, shrinkage, resistance against fire and fatigue. As the technology keeps progressing, the use of fiber reinforced concrete is still growing and expanding continuously. Its technical considerations should be taken care before the design and texture is determined.
The quality characteristics are measured depending upon the type of fiber used, the proportional mix of the fiber, its measure volumes and many more. The more properly the elements are mixed, the stronger the concrete will be. Also, this enhances shear resistance and ductility of the fiber reinforced concrete. Glass, polyester, cotton, rayon, polythene and steel are some of the materials that are added along with the fiber reinforcement.
