| Resumo: | Concrete is a standardized material whose consistency is measured by the slump, which
has a previously defined acceptability range, but not always respected in the process of tracing
water by the truck mixer operator, causing material losses when returned by the construction
staff, or structural problems, by reducing the strength due water excess. Thus, in this work the
new technologies for slump characterization will be presented, in order to develop an
automation mechanism with the use of sensors and internet of things (IoT), capable of ensuring
the material properties. In this sense, we used the works of Amziane et al (2005), Palazzo et al
(1989), and Nagarajan et al (2020), as well as NBR 7212 (2012), and others developed within
this area. Preliminary studies point to the possibility of use sensors inside the concrete plant,
installed in truck mixer, in order to obtain reliable slump results. As well as for the use of
machine learning to identify the degree of fluidity, at the time of dosing. |
