Estudo comparativo quanto ao consumo de aço em estrutura de um edifício de 8 pavimentos com execução de alvenaria de vedação em bloco de concreto celular autoclavado e tijolo cerâmico

Abstract

This comparative study analyzed the steel consumption required for the structure of an eight-story building in Divinópolis (MG), comparing curtain wall masonry in autoclaved aerated concrete block (AAC) and ceramic brick. The goal was to identify which material would provide greater resource use efficiency for the execution of the curtain wall, particularly considering steel, crucial for sustainability and economy in the construction sector. The case study methodology included a comparative analysis based on architectural project data and structural calculations following current technical standards. The results indicate that the use of AAC, due to its lower density, significantly reduces the load on the structure, resulting in lower steel consumption. AAC offers an opportunity to advance towards more sustainable construction practices, yet its adoption requires a careful and comprehensive analysis, balancing environmental and economic benefits with potential difficulties and limitations.
