The dredging operation dislodges sediments from the seabed, and the retrieved materials,<br>termed dredged marine soils, are considered a geowaste for dumping. Therefore reusing the material will<br>benefit the civil sectors, and one option is solidifying with other materials, which are, cement, ground<br>granulated blast furnace slag (GGBS) and sand. The present investigation is on a dredged marine soil (DMS)<br>from Kuala Perlis state in Malaysia where in a laboratory study was undertaken to contemplate the<br>compressibility characteristics of DMS with cement, GGBS and sand admixtures. Cement is the major<br>constituent of concrete which is produced by natural raw materials like limestone rock, clay and chalk etc.<br>These are produced by blasting quarries. Industrial wastes like Ground Granulated Blast Furnace Slag (GGBS)<br>show chemical properties similar to cement. An attempt was made to understand the influence of cement plus<br>GGBS as binder and sand as a granular material by studying the improved settlement rate of consolidation.<br>The results showed that the optimum binder content was from 3C7G_20 specimen and when sand was added<br>to it, it present that settlement decreased with increasing sand content. Binder combinations involving ratio of<br>cement to GGBS of 3 to 7 with addition of sand were effective in improving the settlement and consolidation<br>rate when compared to the performance of cement alone as binder.</p> ER -
