Ferramenta computacional para auxílio na estimativa do custo das perdas na produção in loco de concreto armado

Abstract

The concrete production in construction sites inevitably leads to the waste of some of this material. In an increasingly competitive market in the construction sector, the waste of materials becomes unfeasible both from an economic point of view, unnecessarily burdening construction, and environmental, increasing the generation of waste in the sector. Therefore, the present work aims to estimate the possible cost of these losses and to evaluate them as avoidable or unavoidable. For this, was implemented, in the MATrix LABoratory (MATLAB) language, a computational tool with its own graphical interface and executable on any computer equipped with the Windows operating system. From the program created, the analysis of the losses in the production of concrete in loco was made in a building in the city of Delmiro Gouveia-Al. It was concluded, in the case study carried out, that the cost associated with the wastage of inputs was considerably high, reaching a little more than 21% of the total cost of the concrete produced.
