Experimental assessment of swelling potential in montmorillonite soils

Swelling of Montmorillonite in Polar Organic Liquids

-The crystalline and osmotic swelling of N~, Cs-, Mgand Ca-montmorillonite has been measured in dimethyl sulphoxide and in formamide, N-methyl formamide, dimethyl formamide, N-methyl acetamide and dimethyl acetamide. These liquids have similar dipole moments but their relative permittivities vary appreciably from values less than water to values greater than water. Na montmorillonite exhibits o...

Assessment of Phytoremediation Potential of Alyssum Maritimum in Remediation of Lead-Contaminated Soils

Background and Aim: Phytoremediation is a promising method for improving soils that can easily absorb heavy metals, resulting in decontamination of the soil. The objective of this study was to assess the phytoremediation potential of Alyssum maritimum in the remediation of lead-contaminated soil. Materials and Methods: A randomized complete block design was used with five levels of lead (Pb) c...

Relation between swelling and erodibility of cohesive soils

CHANGE OF b-DIMENSION WITH SWELLING OF MONTMORILLONITE

-The effect of swelling on the b-dimension of Na-saturated, Upton, Wyoming montmorillonite was re-examined using powdered silicon as an internal standard. After being corrected with reference to the internal standard, the b-dimension did not increase through the entire range of swelling as reported previously. It increased up to a water content of ~ 3.0 g/g montmorillonite and remained constant...
