Dewatering and Stabilizing Fine-Grained Soils with Very High Moisture Content

CODEN: ACEMF9

Abstract

The primary objective of this paper is to evaluate the feasibility and subsequent properties of rapidly dewatering fine-grained soils with polymers and stabilizing them with Portland cement. Rapidly dewatering very high moisture soil (VHMS) from 10 % to 30 % solids for immediate re-use in a disaster environment appears feasible. The most feasible application would be saltwater slurry with a relatively low organic content [e.g., high-plasticity clay (CH) soil along a coastline]. Handling contaminated sediments in a disaster environment appears to be a suitable application. Using polymers improved shear strength and elastic modulus of cement-stabilized VHMS. On average, shear strength and elastic modulus improved 25 % and 63 %, respectively. Shear strengths of the materials produced ranged from soft to stiff clay after up to 7 days of curing, which is a useable strength for several applications.
