Stabilized Very High–Moisture Dredged Soil: Relative Behavior of Portland-Limestone Cement and Ordinary Portland Cement
AbstractImprovement of poor engineering properties for very high–moisture content fine-grained soils (VHMS) is important for several industries, including dredging. This paper focuses on improving engineering properties of VHMS by way of adding low dosages of portland-limestone cement (PLC) such as ASTM C595 Type IL, which is a more sustainable alternative to ordinary portland cement (OPC) such as ASTM C150 Type I. A key goal was to determine if PLC can satisfactorily enhance the properties of lightly cemented (LC) VHMS (LC-VHMS), defined as having 5% or less cement by total mass. This paper focuses exclusively on the behavior of PLC versus OPC by making use of five matched pairs of OPCs and PLCs from four different cement manufacturing facilities. A series of index property, unconfined compression (UC), and unconsolidated undrained (UU) triaxial tests were performed on LC-VHMS samples collected from a dredged disposal facility near the port of Mobile, Alabama. Overall, the results suggested that using PLC in LC-VHMS can provide a sustainable alternative to OPC while leading to comparable engineering properties (5% stronger to 8% weaker overall depending on the test type).
