Rheological and Mechanical Characterization of Concrete

The appearance of new concretes increases the need to reliably characterize the behavior of concrete when flowing. The importance of the rheology and its measurement can be certified by the existing literature on the characterization of fresh concrete. In addition to traditional experimental methods such as the V-funnel, slump flow, sieve stability test and the L-box, a new Rheological characterization test has been used: it is the flow of concrete first in a V-Funnel and then in a horizontal plexiglas channel. The main objective of this test is to determine both the flow time in the V-Funnel (indicator of the viscosity of mixture) and the threshold shear of concrete by means of a single rheological test.
