Abstract. Particles size distribution (PSD) is introduced as a tool for analysis of bentonite aggregation and swelling kinetics. Raw Ca-bentonite was purified using a combined wet sieving and sedimentation processes, followed by thermochemical treatment with Na 2 CO 3 to increase its swelling capacity. The detailed analysis of the PSD shows a strong
