DESCRIPTION:The rheological behaviour of vibratable castables is of great i
 mportance for their performance and practical application. This study asse
 sses the reproducibility and accuracy of the conventional slump test in ev
 aluating castable flowability. Three model vibratable castable formulation
 s with q-values of 0.28\, 0.31\, and 0.34 were analysed. Key variables suc
 h as varying oil amounts on the vibration table and the influence of diffe
 rent operators on measuring spread dimensions were examined. Furthermore\,
  the efficacy of 3D spread flow measurements using an integrated 3D camera
  was investigated as an advanced alternative to the conventional slump tes
 t. The system demonstrated sensitivity to oil quantity\, with increased oi
 l on the vibration table augmenting spread flow but also increasing measur
 ement deviation. The findings also revealed a robust correlation between s
 pread flow measurements obtained with calipers and those recorded using a 
 3D camera\, thereby enhancing measurement precision. The 3D spread flow te
 chnique demonstrated superiority in capturing complex rheological behaviou
 rs\, enabling the quantification and comparison of flow velocity and shear
  rate during vibration across different formulations. Each formulation dis
 plays distinct shear rates and flow profiles\, underscoring variations att
 ributable to differing q-values.\nThis study highlights the potential of i
 ncorporating 3D spread flow techniques into standard testing protocols\, p
 roviding refined insights into the rheological properties and overall perf
 ormance of castables. The advanced method enables the optimisation of cast
 able formulations for industrial applications.
