The influence of coloured dyes on the undrained shear strength of kaolin
The influence of coloured dyes on the undrained shear strength of kaolin
Colouring of clay with dyes can be a useful method for monitoring processes in physical modelling where different soil masses interact. In the present study, centrifuge modelling of the interaction of a submarine slide and a model seabed necessitated the addition of coloured dyes to aid differentiation of the slide and the seabed after a slide event. Assessments of pH, index properties and undrained shear strength, supported by Scanning Electron Microscopy (SEM) and X-Ray Diffraction studies, have been used to understand the influence of different dyes on kaolin clay. The addition of different dyes was found to influence the intact undrained shear strength (s u-int) of the dyed samples while the remoulded shear strength (s u-rem) was similar for all samples. XRD and SEM tests revealed micro-structural changes in the dyed samples which may have caused the increase in s u-int.

Abstract
Colouring of clay with dyes can be a useful method for monitoring processes in physical modelling where different soil masses interact. In the present study, centrifuge modelling of the interaction of a submarine slide and a model seabed necessitated the addition of coloured dyes to aid differentiation of the slide and the seabed after a slide event. Assessments of pH, index properties and undrained shear strength, supported by Scanning Electron Microscopy (SEM) and X-Ray Diffraction studies, have been used to understand the influence of different dyes on kaolin clay. The addition of different dyes was found to influence the intact undrained shear strength (s u-int) of the dyed samples while the remoulded shear strength (s u-rem) was similar for all samples. XRD and SEM tests revealed micro-structural changes in the dyed samples which may have caused the increase in s u-int.
