Análise comparativa entre os sistemas construtivos: paredes de concreto moldadas no local e o método convencional de alvenaria com blocos cerâmicos

Abstract

The use of new construction techniques has increased greatly in our country lately. As a result of Brazil`s economic crisis, the application of rational construction methods, which can positively impact the building costs, is extremely crucial, mainly due to the fact that programs such as “Minha Casa Minha Vida” must be continued. One of these techniques is the use of cast-in-place concrete walls system, which has the great advantage of reducing waste, time, material costs and labour costs. Therefore, the main goal of this paper is to show a comparative study between the current conventional technique consisting of masonry walls and the cast-in-place concrete walls system, having as support the analysis of a standard building with 55.44 square meters of area. This standard building was designed for the two systems mentioned before, verifying two parameters: cost reduction and time decrease. Further, the results obtained by this study were discussed through cost estimating and graphical analysis. By doing so, it was possible to verify if the cast-in-place concrete walls technique is financially viable for this project
