The effect of low to moderate organic content on the engineering properties of a remoulded marine sediment was investigated by classification tests, undrained shear strength tests, consolidation tests and triaxial compression tests. Sediment with a naturally occurring organic content of 2%, was treated to provide 0,3, and 4% organic matter; first by reaction with hydrogen peroxide to remove the organic matter and then by addition of a naturally occurring humic compound in the latter two cases. In its natural state the sediment was classified as an inorganic sediment of low plasticity. Addition of the stated amounts of organic content did not result in the sediment being classified as organic; however, the remoulded undrained shear strength, the compressibility, and the rheological behavlour of the sediment were significantly affected by the variations in the organic content. By contrast, the effects of these variations on the specific gravity, permeability, rate of consolidation and consolidated-undrained shear strength were not very marked.
