Rheological characterization of self‐compacting concrete: New recommendation

The most commonly used test to characterize the fluidity of self‐compacting concretes (SCC) is the Abrams cone spreading. However, this later, according to many scientific studies, contains some defects depending on the operator and the analysis of the found results. Further, the use of a concrete rheometer on building site is a very complex operation. In this regard, our laboratory has developed another practical, simple, and economical test able to measure, on building site, the plastic viscosity and the yield stress of the SCC. This is a “V‐Funnel coupled to a horizontal Plexiglas channel” test. The experimental results of our study show that the proposed tool can replace the LCPC‐box test, the concrete rheometer and other empirical tests recommended by the European standards.
