| Resumo: | Technological control of concrete consists of a set of operations that seeks to guarantee the quality of the material and encompasses from its production to the verification of its characteristics when already in service. The ABNT NBR 12655:2015 standardizes these procedures in Brazil and uses the compressive strength of concrete, through a statistical approach, as the main property to measure the degree of conformity of the material. However, there are not rare cases of construction works in the country with problems related to the conformity of concrete and this justifies the study of the standard in order to clarify the current methodology and its subsequent application in example cases to illustrate the practical process of standard using. It is concluded that the control procedures still do not receive adequate attention, both due to the lack of academic dissemination of the subject and the lack of understanding, on the part of the professional body, of the implications, in their entirety, of a non conforming concrete to a structure. |
