Experimental Study on the Mechanical Behavior of High Water Content Dredged Materials Stabilized by Cement and Super-absorb Polymer

摘要

A series of unconfined compression strength test and odeometer test were conducted to study the mechanical behavior of cement stabilized dredged material at high water content with super-absorb polymer. The super-absorbent polymer (SAP) is added as water reducing agent into the cementing agent to improve the effectiveness of cementation for high water content dredged material. Test results show that the unconfined compressive strength (q_u) increases with increasing SAP content, the strength increase is about 2.4 times when SAP content is of 10‰. For certain cement content, the compression curve of cement stabilized clay with higher SAP content lies blow that of lower ones, as a result, the vertical yield stress (σ'_(vy)) increase with the SAP content.
