Análise financeira comparativa entre paredes de concreto armado e paredes de concreto com adição de fibras de vidro: estudo de caso

Abstract

Currently, there has been a search for innovation and progress in the construction industry, regarding the introduction of glass fibers in reinforced concrete, with the purpose of being an alternative for a possible reduction in the consumption of steel in reinforced concrete wall works, which is an input with a constant increase in cost in the market. This work has the general objective of showing, through a comparative case study, the direct costs of reinforced concrete wall construction systems and fiberglass reinforced concrete walls. This is a bibliographic, descriptive study, applied research and comparative case study of a survey on site, where data was collected on a site carried out by a construction company that operates strongly in the social housing sector. The study demonstrated that construction methods have been improved in recent years through structural solutions that incorporate concepts of sustainability, performance and productivity in civil construction, in order to obtain a product with better quality and at a reduced cost. In view of this, it was identified through the cost comparison between the aforementioned construction systems that the fiberglass reinforced concrete wall presents characteristics that can help the engineer in making a decision between the alternative construction methods. In terms of economic viability, this alternative can result in savings of approximately R$ 20,000.00 compared to the traditional reinforced concrete wall method. In addition, it offers advantages such as sustainability, performance and productivity, making it an effective alternative that can be competitive in the civil construction market.
