Lime-treated specimens, especially those with higher lime dosages (4% and 6%) due to their lesser adherence to the container surface owing to a decrease in plasticity resulted in a smaller width and spacing of cracking as well as a large number of clay...

In particular, sedimentation behaviours were compared between negatively charged natural kaolin clays and surface-treated and hence electrically...
