ESTUDO COMPARATIVO DOS CONCRETOS USINADOS E PRODUZIDOS EM OBRAS DE PEQUENO E MÉDIO PORTE EM LAMBARI MG

Abstract

Nowadays, there are numerous ways of producing concrete and the most common are concrete produced at construction sites and concrete produced by a machining center. Rolled concrete on site is the most used for the concreting of small works, since it is impossible to hire a low volume of machined concrete. The research aims to compare the compressive strength of cast concrete samples on site and machined concrete. Thus, 7 works were chosen in the city of Lambari - MG, to collect the material. Where 5 works were harvested, the concrete cast on site and 2 works were harvested from machined concrete. The tests were carried out in the laboratory using a hydraulic press. Finally, after the experiment, it was found that the machined concrete presented a satisfactory result, in terms of compressive strength.
