smectiteexperimental investigationcement pore fluidhigh pHcation exchangestabilityXRDThe aim of this study is to examine the effect of various high pH solutions on smectites. The starting materials were a Na,Ca-smectite and two homoionic Na- and Ca-smectites. The experimental solutions were 0.01 m...
Clay-modified electrodes (CMEs) were prepared with two synthetic cobalt smectites. Large increases in the peak currents were observed in the cyclic voltammograms of tris(2,2'-bipyridyl) metal cations ([M(bpy)3]2+, M = Os, Fe, or Ru) adso... Y Xiang,G Villemure - 《Journal of Phys...
Lattice-fringe images showed that smectite equilibrated in aqueous, low-ionic-strength solutions, exists as individual smectite layers, osmotic hydrates composed of parallel layers, as well as disordered layer conformations. No evidence was found here for edge-to-sheet attractions, but significant ...
A Ca-smectite which may be suitable as buffer material for nuclear-waste disposal is being investigated in a cooperative research project of Sweden and France. In this article the strength-,compression-, and swelling-properties of this clay are described. Some important conclusions of the test ...

Alteration minerals consist of calcite, sulfate, smectite and chlorite/smectite associated with Cu-rich sulfides. The mass balance calculations from less altered to altered volcanic rocks show large chemical changes with the mobility of mettallic elements in major or trace amounts. Mass balance ...
