2016114· All the materials used without any disposal. The illite-, hematite- and limonite-montmorillonite mixtures were prepared by mixing 90 wt% montmorillonite with 10 wt% illite, hematite and limonite uniformly. The clays were compacted in the cylinders with diameter of 2.57 cm and thickness of 0.90 cm to obtain the dry density of 1600 kg/m 3.
