Studies on Soil Cements: 1 - Role of Hydrated Lime and Dolomitic Monohydrate in Montmorillonite Stabilization
MetadataShow full item record
Montmorillonite clay was stabilized by either hydrated lime or the dolomitic monohydrate (Ca(OH)2. MgO) during suspension hydration at 25 and 60°C for 45 days. The distinct phases produced from the hydration of each stabilized clay suspension were identified by means of X-ray diffraction analysis. The role of either Ca(OH)2 and/or MgO in soil stabilization could be clearly understood in order to extend the use of portland cement for the stabilization of montmorillonite to produce soil cements.
