Effect of Curing Stress on Compression Behavior of Cement-Treated Dredged Sediment

Abstract

The curing stress is an important parameter affecting the mechanical properties of the cement-treated soil. This paper presents the effects of curing stress on the compressive and physical properties of the cement-treated dredged sediment (CDS). The plasticity behavior of CDS is affected by both the cement content and curing stress, whereas the particle size of CDS is mainly influenced by the cement content. The curing stress can reduce the compressibility of CDS significantly and slightly change the compression behavior of the postyielding stage, which is related to the structural behavior of CDS in the compression process. Finally, the strength factor related to the curing stress and cement content was proposed to predict the strength of CDS.
