Stabilizing Very High Moisture Content Fine Grained Soils: Early Age Strength and Later Age Property Correlations
Recently, chemical stabilization has gained attention for high moisture fine-grained soils, due at least partially to increased sustainability and beneficial use desires. As defined herein, very high moisture soil (VHMS) is at a moisture content at or above the soil’s liquid limit. Cases where VHMS is chemically stabilized with 5% or more cementitious material by total VHMS mass is referred to as cemented VHMS (C-VHMS). A primary objective of this paper is to compare portland cement to blended portland and slag cement for C-VHMS at early ages. Another objective is to determine strength, modulus, and ductility properties of C-VHMS over a period of several months to establish strength to modulus correlations. All other factors constant, slag cement’s strength gain potential is greater at later ages than at early ages, and as such, sluggish early strength gain that can be problematic was evaluated a considerable amount in this paper.
