Extrusion rheometer for 3D concrete printing

Cement and Concrete Composites, 2021
Abstract An ability to measure and monitor the rheological characteristics of concrete is important for 3D printing applications. Printable concretes need to have high yield stress and viscosity for buildability. The common rheological testing methods, such as slump tests and rheometers are not sensitive for these highly stiff concretes.
