81-B0120/B with thermometer

Viscosity corresponds to the resistance of a liquid to flowing, so it’s a parameter strictly related to binder consistency and workability. Binder viscosity is heavily affected by temperature, and is measured using different methods such as measuring the time needed to pass through a capillary (kinematic and dynamic viscosity), an orifice (Standard TAR, Engler and Saybolt viscosity) or the force needed to rotate two coaxial cylinders (Rotational viscometer).
