ANALYSIS OF AESTHETICS OF CONCRETE PRODUCED WITH PLASTIC REJECT FOR USE IN SUSTAINABLE INTERIOR DESIGN

Abstract

Concrete is widely used because of its cost-benefit ratio: no other building material concomitantly has these two advantages. However, excessive use of concrete in construction is responsible for an increase in cement production and transportation. In addition to this disadvantage, the increase in waste generation and the exploitation of natural resources from material production is a progressive problem and, consequently, the ecological balance is negatively affected. The aim of this work is to evaluate the aesthetics of concrete produced with recycled plastic waste, for use in interior design and furniture objects. The proposal unites the reuse of these plastic materials that are problematic for society and the reduction of cement waste. To this end, a brief analysis of the reframing of the use of concrete as not only structural, but with aesthetic value, was carried out in interior projects whereconcepts about sustainability and sustainable development are presented, as well as issues about plastic disposal and recycling.The methodology used included the preparation of concrete with different proportions of plastic waste, preparation of specimens and later tests performed in the laboratory to verify the loss of mass and porosity of the produced part, for the purpose of use. The results indicate that the study contributes to the reduction of plastic waste, producing a material that is ecologically balanced and of satisfactory aesthetics when compared to concrete without the addition of plastic waste.
