ABSTRACT
Dyes contain chemicals that may change the microstructure or influence the interparticle attraction forces and can ultimately cause changes in the geotechnical properties of a clay. To quantify the effects of different dyes on the geotechnical properties of kaolin clay, pH tests, basic index testing as well as assessment of the shear strength from T-bar penetrometer tests were carried out. Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) studies were also utilised to investigate the influence of dyes on the micro-fabric of the samples.
