Análise da influência do resíduo de borracha de pneu nas propriedades do concreto

Abstract

This present undergraduate thesis is about the analysis of the properties of concrecte with the influence of tire rubber residue addition. There were added into the concrete masses the proportion of 5 and 10% in function of the cement amount used for the trace. It has also done the same concrete trace without addition of residues, so it could be verified the possible variations in the properties of the concrete in the hard-bitten state. There has been performed in laboratory tests to make a comparison between the concrete with addition of waste proportion and the reference concrete. Therefore, there has been performed compression strength tests, tests for determination of absorption by immersion and boiling, for the determination of void index and specific mass. In this way, it has turned out the reduction of compressive strength in concretes with the addition of residues, being 26.90%, for concrete with 5% residue and 56.64% for concrete with 10% residue. It has also performed an increase absorption and void indices, which also contributed to decreased compressive strength.
