CARACTERIZAÇÃO DAS PROPRIEDADES MECÂNICAS DE MISTURA DE TERRA-POLIÉSTER ORIUNDO DE EDREDONS USADOS

Abstract

Use of materials and construction techniques that maintain quality of life and allied to sustainability in construction and use. Earthen construction is a low-impact alternative that has been used for hundreds of years. Polyester is an easily available material used as thermal insulation. Thus, the present work aims to study the mechanical behavior of earth-polyester mixtures as a construction material. The mixture was prepared with soil (sand and silt) and a percentage of polyester reused from recycled duvets (at 1.25% and 5%). Mechanical tests were performed in a SCHENCK compression machine. Thus, the soil-polyester mixture showed good mechanical properties, which are important for a good building material. However, comparing the two types of samples, the mixture with 5% polyester has the best results. Thus, it can be concluded that the use of these materials is positive in civil construction because the use of recycled fibers does not reduce the mechanical strength when compared to traditional earth constructions. Furthermore, the use of fibers incorporated in construction matrices contributes to the insulating capacity that reduces the consumption of electricity with the use of thermal comfort equipment, thus contributing to sustainable development.
