Geotechnical Properties of Crushed Cement-Stabilized Sludge and Its Trial Application to Vertical Drain
Abstract:As an effective reuse method of surplus soil and sludge, the authors proposed the crushed cement-stabilized sludge which is made of cement, polymer, surplus soil and dewatered sludge. Its geotechnical properties and applicability to the drainage material in sand drain and sand compaction pile methods were investigated. The geotechnical properties were almost similar to those of general granular materials except high alkaline. The crushed cement-stabilized sludge was applicable to the dranage material judging from its acceleration effect of soil consolidation.
