Dosagens do concreto para o controle de qualidade de estruturas pré-moldadas: estudo de caso

Abstract

Nowadays, civil engineering is in the era of concrete, where its use is almost always used in all types of works. However, the construction industry is considered to be backward in comparison to other industrial sectors. To improve this negative characteristic there are several alternatives, among them is the use of precast, which reduces construction time, solid waste production, wastage of materials and increased speed of execution of the construction site. This study aims to improve the quality of precast concrete of a specific company, considering the relation between its costs and its benefits, and also, maintaining the quality standards imposed by the projects, by changing the concrete dosages used and obtaining results by the compression tests. From the tests performed, it was possible to observe an improvement of the concrete that was produced before the beginning of this study, in relation to its quality, and its cost was still reduced.
