Desenvolvimento de um sistema construtivo com painéis sanduíches para habitações de baixa renda

Abstract

Brazil is currently suffering a large deficit in social housing, which can be measured based on the population growth, and on the to public housing policies through which it is not possible to provide efficient solutions in terms of quality, execution time and construction methods in line with environmentally friendly approaches and the necessary levels required to achieve a good quality of life. In the light of this, new construction systems have been emerging in the market as solutions, such as precast sandwich panels applied to low-cost housing. This system considers planning, dimensioning and detailing, and for that reason it was included in this research. Based on the problem previously stated, the objective of this work is to develop and characterize sandwich panels made of an expanded polystyrene (EPS) core and ferrocement facings. To accomplish this objective, two types of reinforcement (metallic meshes) for the ferrocement facings were evaluated. With the best reinforcement arrangement, the sandwich panel was produced, and it was characterized by means of mechanical testing (bending) and physical testing (thermal). Moreover, a low-cost housing was designed in line with the bioclimatic characteristics of Manaus, a city in which sandwich panels will be implemented for external and internal walls.
