Análise das propriedades mecânicas de concretos incorporados por fibras e cinza do bagaço de Cana-de-açúcar.

Abstract

This work presents a comparative analysis of the mechanical properties of concretes subjected to the incorporation of sugarcane bagasse fiber (FBC) and sugarcane bagasse ash (CBC) as well as the simultaneous incorporation of these materials, and concretes that are commonly used (without additions). The analysis will be carried out between the results of tests on compressive strength, modulus of elasticity and tensile strength by diametrical compression presented in the work carried out by students Gabriela Silva de Medeiros and Letícia Cristina Teixeira Cavalcante from the Civil Mobility Engineering course at the Federal Institute of Education, Science and Technology of Goiás (IFG) at the Anápolis Campus. It is worth noting that among the percentages studied by the aforementioned authors, new possibilities for additions were studied as a complement, in this case with the percentages of 3%FBC, 7%CBC and 3%FBC+7%CBC. In this way, these new samples were also subjected to the same preparations, tests and conditions as the others studied by the authors, in order to expand the analysis of the behavior of these additions in concrete. For the addition percentages of 3%FBC, 7%CBC and 3%FBC+7%CBC, the curing procedures used, the results of the cone slump tests, and the results of the tensile tests by diametrical compression, compression and modulus of elasticity. Subsequently, through the analysis of the results obtained between the reference concrete and all the concretes with additions discussed in this work, the concrete that presents the best results in terms of tensile strength by diametrical compression, compressive strength and elastic modulus was determined.
