During the concrete production, we attempt to adjust its viscosity to allow optimal implementation. In this article, we have proposed a correlation between the plastic viscosity of concrete, the time, and the characteristics of the flow final profile from the V‐Funnel coupled to a horizontal channel Plexiglas. The proposed approach, verified by experimental results, represents a simple, economical, and usable tool on building site, and it allows to characterize rheologically the concrete from its flow. The comparison between our approach and the experimental values of the plastic viscosity shows that, in a laboratory or on site, instead of using a rheometer, we can use our approach to characterize the rheological behavior of a self‐compacting concrete.
