Análise da viabilidade técnica e econômica da utilização de agregados reciclados para argamassa em emboço de parede interna em obras de pequeno porte

Abstract

The main objective of this work is to analyze whether recycled aggregate, when applied in mortar for the plaster of a small project, is technically and economically viable when compared to natural aggregates. Currently, the construction industry has turned to more eco-efficient practices, improving the work's economic viability and environmental issues, such as reducing and recycling the generated waste. One of the alternatives that can be explored to make a project more eco-efficient is the use of recycled aggregate in the production of mortars. Although research about the use of recycled aggregate is already extensive, there is still little publicity about this alternative. There is resistance from engineers to the use of recycled aggregate onsite due to a lack of knowledge and reliability of the material. In order to show the technical and economic viability of the aggregate, exploratory research was carried out in several bibliographies to clarify how recycled aggregate, when used in non-structural functions on site, has the same or greater technical performance. Also, a simulation of the usage of recycled aggregate on the internal wall plaster of a hypothetical small project was also carried out to exemplify how it is also economically viable. With the research, it was observed that recycled aggregate is technically viable, however economically its viability is compromised due to logistical problems.
