This final chapter summarizes the contents of this State-of-the-Art Report. Mortar or concrete are typically viscoplastic materials, exhibiting a yield stress, followed by linear or non-linear flow behavior once the yield stress is exceeded. Furthermore, the rheological properties are time and shear dependent. The definition of a rheometer from Chap. 3 is reiterated and a summary of different mortar and concrete rheometers, as well as empirical test method capable of deriving certain rheological properties is included. The importance of selecting appropriate measuring procedures, transformation equations and data analysis is highlighted, as well as the significance to consider several measurement challenges. Some applications of measuring properties near interfaces from Chap. 7 are also repeated. Performing rheological measurements is not a straightforward task as selecting an equipment or procedure and analyzing the output is a process of critical thinking, experience and potentially trial-and-error.
