The Influx Of Fiber Reinforcement In Construction.
Monday, April 2, 2012

construction sector has of late come under the lime light due to rampant cases of collapsed buildings. The steel used in many structures as reinforcement is prone to attack by corrosive naturally occurring compounds. Advancement in building technology has led to use of fiber reinforcement as a means of protecting structures from wear. fiber reinforcement
a common alternative to steel is the use of polymers in concrete to improve its properties through chemically formed bonds. This produces a crack resistant composite that is ideal for use in non saline surroundings. Its major limitation is the failure of the bonds when exposed to salt which manifests in surface blistering.
The market has seen an influx of FRC material in the construction industry. The formerly popular steel is now replaced with fibers to produce a composite with superior resistance to cracking due to its high tensile strength. Since most commercially used fiber are byproducts of crude, this method is proving to be a cheaper solution in the long run.
A very popular compound among FRC manufacturers is propylene. This material is shredded into very fine particles which are then vigorously stirred into the concrete during mixing. This procedure will disperse them indiscriminately within the mixture and the resulting composite has improved properties in all directions.
Depending on the desired volume percentage there are two other methods popular with manufacturers. The available material will help to decide whether it is used as continuous network of fibrillated film or as a woven mesh. Though all the materials achieve the intended purpose they bear appealing and non appealing characteristics as well.
Today, commercial products have steel, glass, polypropylene or polyester materials incorporated. The manufacturer chooses the material based on properties such as specific gravity and tensile strength. The reinforcing fibers stretch more than the concrete under stress. In case a crack develops they undergo pullout processes and resist deformation.
All fiber reinforcement producers must subject their products to routine tests as laid out by safety conscious authorities. Being non biodegradable, the amount of effluent the product might release to the environment may be a cause of concern. For this reason, many companies are adopting the option of seriously funding research aimed at bettering the industry.
