Environmental impacts raised from dredging such as turbidity and disturbance of marine ecosystem had<br>increased the social demand to reuse DMS in engineering application. Typically, DMS have low shear<br>strength and low bearing capacity. Hence, the DMS could be strengthened up by soil solidification. In present<br>study, waste granular materials (WGM) such as coal bottom ash (BA) and palm oil clinker (POC) were<br>utilized as additional binder to cement. The DMS were solidified with 3 series of admixtures; namely cement<br>and/or WGM. The factor that influenced the compressibility of the soil sample such as percentages of<br>admixtures were considered. Proportioned samples of 10, 15 and 20 % of cement, and/or 50 and 150 % of<br>WGM of dry weight of DMS were subjected to one-dimensional oedometer test. The test samples were cured<br>for 7 days in room temperature. Results show that cement- and WGM-admixed DMS have reduced the soil’s<br>compressibility considerably than the untreated sample. As expected, the cemented soil had significantly<br>reduced the settlement better than WGM-admixed soil. Hence, homogeneous samples of 15C50BA and<br>10C100POC produced almost similar reduction of compressibility as sample 20C. Therefore, reusing WGM<br>as partial replacement of cement in DMS could provide beneficial reuse of these materials.<br><br></p>}, number={38}, journal={GEOMATE Journal}, author={Mohammad Zawawi Rosman and Chee-Ming Chan}, year={2017}, month={Apr.}, pages={104–110} }
