Utilização de descarte de resíduos têxtil (poliamida/poliester), como agregado, em concreto

Abstract

On this work are present some physical characteristics, advantages and viability of the use of the fabric dust, proceeding from the processing of textile residues that are discarded in confections in general. The production and use of this type of dust diminish the ambient impact and if it shows economically viable, therefore it is produced easily from the processing of residues, which would be discarded in the nature. The present work shows to the study of the production of the dust of tissue its partial substitution of the natural small aggregate in the production of concrete of Portland cement conventional. To prove the viability economic technique and of the use of the fabric dust they had been analyzed characteristic of the aggregate as its grain sized composition, and its behavior in the discouragement assays cone trunk (Slump Test). A relation water-cement also was stipulated to the one usual concrete with resistance waited of 27 MPa. With these data a trace for concrete using 5% and 15% of added fabric dust, substituting was defined the sand. The research presents the results of simple compressive strength of the cylindrical bodies of test of concrete to the 28 days. It was verified so little that the samples had not presented significant differences of resistance between itself, with regard to the resistance of a conventional concrete only produced with natural small aggregate. However, the compression had an improvement in the results of the assays, mainly in the concrete with 15% of fabric dust.
