Abstract

A calcareous and non-calcareous clay were fired to 900 degrees Celsius and subsequently impregnated with a solution of Na2SO4. These test samples were then impregnated with one of three consolidants: Acryloid B72, Tetraethyl Orthosilicate (TEOS), Methyl Triethoxysilane (MTS). Desalination tests using the static immersion and stirred solution methods were made to determine the effect of consolidation on the rate and extent of salt extraction. Desalination was monitored by Ionic Conductivity, Atomic Emission Spectroscopy and Ion Chromatography analysis of the extraction solutions.
