Abstract
Description
Various codes standardise fresh-state concrete characterisation via field testing. The most widely
adopted characterisation measures overlook broader performance issues, including stability, and are
therefore supplemented with subjective judgements. This work reviews qualitative and quantitative ap
proaches and investigates concretes identically characterised using the current approach. Flowability
measures of slump height are compared to yield stress and viscosity values obtained via 3D reconstruc
tion and accelerometers embedded in field tests. Qualitative measures of stability, including the Visual
Stability Index (VSI), are compared to digitally derived measures of circularity, paste separation and
reflectivity. Digital tools deliver quantitative measures, facilitating robust fresh state characterisation.
