A relação de custo-benefício do uso do bloco de concreto celular autoclavado – estudo de caso.

Abstract

: In recent years, the construction industry in Brazil has gone through a phase of recession, caused by political turmoil and the COVID-19 pandemic. To overcome this phase, priority has been given to the use of new technologies, with more agile processes and lower costs. The study of autoclaved cellular concrete blocks, which are made from a mixture of lime, water, sand, cement and an expanding agent (aluminum powder), has been gaining ground in the domestic construction market. The aim of this work was to comparatively analyze the masonry made using the autoclaved cellular concrete block (BCCA) system with the sealing system using ceramic bricks and traditional cladding, so to check whether the cost-benefit ratio implies a reduction in the cost of masonry made using BCCA.
