Análise comparativa entre um sistema construtivo convencional e sistemas construtivos de EPS

Abstract

In a country with great use of construction systems aimed at increasing productivity as a solution to housing shortage rates, the dissemination and the knowledge of other innovative construction systems are necessary to contribute to the discussion of gains in time and costs as a result of the type of construction chosen. Thus, this work aims to demonstrate the technical and financial viability of innovative building systems that use expanded polystyrene (EPS) in their composition. For this purpose, productivity and cost indexes of a social housing were compared on the conventional construction system, that is, composed of reinforced concrete structures of columns, beams and slabs, combined with sealing blocks. From the analysis and results presented, it was found that EPS systems have significantly higher costs when compared to the conventional system, mainly due to the price of EPS component panels. In addition, there was a gain in time when using expanded polystyrene systems, which demands, using monolitic panels, 9 working days less than the conventional system, and 5 working days less when using the ICF (Insulated Concrete Forms) system. However, in the context of social interest housing, the use of expanded polystyrene systems did not prove to be attractive, due to the higher cost and not so significant gains in the construction process duration.
