Many of the bounties and resources of the earth like iron, nickel and other metals are used in creating metals. Iron is alloyed with carbon to form carbon steel and there are a number of different techniques to derive alloy steel. These modifications due to the inclusion of various alloying elements enhance the metal’s features. It also gives intentional attributes and attributes to the alloy which aren’t present in the element alone. Steel rebars may be available and a strong durable material used, popularly, in construction projects worldwide. However, what if another material was also available which is 3 times more powerful, has a life expectancy 5 times more than steel and cost-effective, trustworthy and downright sensible.
GFRP Rebar has been around for a while but due to several reasons, that doesn’t really have anything to do with its qualities and features, has not seen the enormous market share of growth as it should. A variety of factors contribute to the situation including commercial motives and opposing business entities that are catering to self-interests. Also, despite large-scale recommendations and certificate from civil engineering associations of steel as dependable and reliable overshadowing much of the rising trend of using a composite material in their infrastructural and structure, this lightweight, sturdy material is here to stay. With establishments and entities making their own guidelines for the usage of GFRP, this revolution in civil engineering is doing a hundred twenty on the information highway and going places fast.
The benefits of GFRP rebar outweigh those of steel in many ways. Beginning with steel, its safe to conclude that some, while not all, rehab needs rise around ten years following conclusion but others need major rehabilitation in no more than twenty years. Also, because of corrosion and weather effects, steel loses stability and deteriorates. Another disadvantage of steel is its massive weight. Its heavy and cumbersome work lifting and transporting steel rebars. Envision the workload of an average employee and the amount of work required to install steel. Its sturdy strength is brought together with fantastic weight. Delivering a project can be delayed because of completion problems and many do happen during installation phases. Shipping and mobilization costs are high and more manpower is required to be able to complete as per schedule.
In comparison with steel, glass-fiber reinforced polymer rebar has a shelf life of above a hundred years, so rehabilitation work isn’t required soon. It does erode nor rust. Totally resistant to weather conditions and even bears moisture attacks with grace making it non-susceptible to chemicals and water. It’s lightweight with being 1/3 times milder by ratio-wise comparison against steel. Easy in loading and highly resistant to damage while transporting. Utilizing it also increases the odds of finishing a project well before time as it is easily handled and installed. By choosing GFRP rebars, prices are lowered with less manpower and shipping expenditures.
