Abstract
The 2n mixing theory was developed with the concept of Japanese noodle (UDON) making method. The mixing of dredging sludge was done with 20% (by volume) of expanded-poly-styrene beads in 15 units of M–Y Mixer using the cement paste. Samples were taken at starting, middle and end level of continuous mixing. Average unit weight was 1.07 gm/cm3, with its variation coefficient of 2.68%. Average 28 days compressive strength was 7.04 MPa, with a variation coefficient of 3.66%. The efficiency of the M–Y mixer was sufficient for continuous mixing of dredging sludge, giving required compressive strength for soil settlement.
