Análise comparativa entre os sistemas construtivos de vedação entre os sistemas construtivos de vedação em alvenaria de blocos cerâmicos e com painéis monolíticos em EPS

Abstract

The search for new construction techniques makes optimized systems gain space in civil construction, monolithic panels with expanded polystyrene (EPS) core, in addition to reducing the structure's own weight and optimizing the thermal-acoustic performance, are able to minimize the total cost of the structure. The EPS panels are composed of a steel mesh, reinforcements, after their assembly, they are coated with concrete or resistant mortar. The influence on the sizing of the structure and the impact of the total cost of the work was evaluated using the monolithic panels in EPS and conventional walls of ceramic blocks, with the objective of determining the most advantageous method, capable of providing the reduction of the necessary inputs for execution and of the total cost of the work. For this, through a 3-story multifamily building project, with a total area of 411.82 m², both vertical fence systems were designed according to NBR 6118 (ABNT, 2014), the total amount of steel used in the structure was obtained, and the quantity of concrete in each construction method. There was a reduction in the amount of concrete of 4.14% in the building using the monolithic EPS panels; in relation to the quantity of steel, a reduction of 11.32% was obtained. The adoption of monolithic EPS panels in the construction proved to be advantageous in relation to the total budget of the structure and fences. Where the foundation's budget was reduced by 2.62%, representing a savings of BRL 7,156.37.
