Estudo da aderência de argamassa produzida com agregado polimérico.

Abstract

Population growth and urban development are intrinsically related to increased waste production, and it is necessary to develop techniques for such growth to occur in a sustainable manner and to contribute to the reduction of waste production and to provide adequate disposal. Currently, the industry is responsible for the generation of various wastes, especially ethylene politerephthalate (PET), which occupies a prominent volume in the dumps. In this sense, it is feasible to give it destinations that provide longer service life without completely discarding it, such as incorporating it into building materials. This research aims to evaluate the adhesion of mortars produced with replacement of conventional aggregate by polymeric aggregate in the contents of 5,10, 15, 20 and 25%. The tensile strength of the panels will be determined according to NBR 13528 (ABNT, 2010). The results indicated that mortars with a substitution content of up to 5% of the fine aggregate for polymeric aggregate can be used in external and internal cladding, and with a content of up to 15% in internal cladding, and the material, previously discarded, can be inserted in the productive chain.
