Title: OVERCONSOLIDATED BEHAVIOR OF PHOSPHORIC ACID AND LIME-STABILIZED KAOLIN CLAY
Accession Number: 00611901
Record Type: Component
Availability: Find a library where document is available Abstract: Consolidation and shear strength properties of a kaolin clay stabilized with hydrated lime or phosphoric acid were investigated. Consolidation test results indicated that lime or phosphoric acid treatments cause a chemically induced preconsolidation effect of the normally consolidated kaolin clay. The overconsolidation behavior caused by chemical addition is influenced by the type and amount of chemicals and the applied original preconsolidation pressure. Lime or phosphoric acid also decreases the rebound compressibility index of kaolin clay. Consolidated, undrained, shear box tests indicate that the addition of lime or phosphoric acid to clay increases its cohesion and its angle of internal friction and that the strength gain of chemically treated clay is improved and accelerated by consolidation with aging. These findings encourage consideration of chemical treatment as a possible alternative for the control of settlements of kaolin clayey soils.
