PREVISÃO DO IMPACTO DA ADIÇÃO DE RESÍDUO DE BORRACHA DE PNEU NO DESEMPENHO MECÂNICO DO CONCRETO

Abstract

For sustainable reason, it is important to evaluate the influence of rubber waste from worn out tires on the mechanical performance of cementitious composites. With this purpose, a database was created containing the characteristics of concrete added with rubber waste. So, the mechanical performance could be analyzed through outlier’s tests, normality tests and frequency tests. After that, a model of regression was made with the variables: rubber size, rubber content, water/cement ratio and resistance to compression. With the results it was possible to present the tendency of the mechanical behavior of the cementitious composite with rubber residues.
