Avaliação da viabilidade econômica da utilização de concreto de alto desempenho e lajes planas protendidas em edifício residencial estudo de caso

Abstract

The high performance concrete is recognized and successfully used internationally as a possible substitute for the steel as a construction material. The Brazilian situation, despite a few sporadic good examples, is different and full of practical and project gaps. Therefore, the purpose of this research is to evaluate the economic viability of the use of high performance concrete in a building. The adopted procedure goes through the full structural project (including foundations) of two buildings, one of them with conventional structure and the other with high performance concrete. Not till then, it was possible to determine costs and an estimate of direct and indirect economic results. Finally, the conclusions obtained are seen as an important source of information besides being a guiding aspect not only for the use of high performance concrete, but also for the accomplishment of more studies about it.
