    Effect of using Cement Kiln Dust as a nano-material on the strength of cement mortars by Alnahhal, Wael

    Published 2017
    “…The CKD was milled up to 4 hours in a planetary ball mill. In addition to the control cement mortar mixture with 0% CKD, a total of 28 concrete mortar mixtures were prepared with four different replacement percentages of nano-CKD (5, 10, 15, and 20 %), and seven different milling times (1, 1.5, 2, 2.5, 3, 3.5, and 4 hours). …”

    Colloid retention and mobilization mechanisms under different physicochemical conditions in porous media: A micromodel study by Nishad, Safna

    Published 2021
    “…However, for hydrophobic colloids, changes in solution chemistry significantly increase colloid retention where the colloid interaction become attractive with the increase in ionic strength and decrease in pH values. Colloids attached to the collector surfaces mobilized by the strong capillary forces induced by the moving gas-water interface and transported along with the interface. …”
