Time-Dependent Properties of Very High Moisture Content Fine Grained Soils Stabilized with Portland and Slag Cement
Recently, chemical stabilization applications seem to be expanding, in particular stabilizing fine-grained soils with elevated moisture. In this paper, very high moisture soils (VHMS) chemically stabilized with 5% or more cementitious material by total mass are referred to as cemented VHMS, or C-VHMS. This paper’s primary objective is to evaluate strength gain of C-VHMS over time and use the measured properties to evaluate usefulness for various applications. A secondary objective is to compare properties of Portland cement to blended Portland and slag cement within C-VHMS. C-VHMS strength properties were reported from mixing through 180 days of curing on two soils. Results showed Portland and slag cement blends were able to produce on the order of 67% of compacted soil-cement (albeit with considerably different total dosage rates) in one of the soils. Overall, C-VHMS, when allowed sufficient curing time, was shown to be more robust than intuition might suggest.
