Estudo da substituição da fibra ótica por fibra de poliamida para produção de concreto translúcido visando aplicação em ondulações transversais em vias públicas

Abstract

The translucent concrete is a variation of concrete which allows light to pass, from one side to another of an specimen. This is possible because of the addiction of optical fiber on its composition. The translucent concrete is a high cost material, due the use of optical fiber on its productive process. This study presents an investigation about the replacement of optical fiber with polyamide fiber (fishing line) on the execution of translucent concrete, performing experiments for initial characterization of the aggregates and later of the concrete with the added alternative material. The main tests are compression rupture and translucency. The results obtained are used to make comparisons with existing data from the literature, at the final presenting a comparative percentage between the concretes executed with the abovementioned materials, to judge the cost benefit of the "fishing line" used in the substitution. After the tests were carried out, it was verified the economic feasibility of using polyamide as a substitute for the fiber. However, this would need to be added to the composition in greater quantity. Due to this larger volume of polyamide, a study for evaluantion the concrete strength increase is necessary.
