The fine-grained nature of the DM and the presence of high sulfate concentrations (0.6–3.25% by weight) in the stabilized dredged material (SDM) blends derived from the raw materials themselves posed concern for potential ettringite formation and swell. The sulfate contents of the SDM blends were well in excess of the National Lime Association’s thresholds for mitigating against swell ( DEWEY : 624.1 ISSN : 1090-0241 En ligne : http://ascelibrary.org/gto/resource/1/jggefk/v138/i3/p407_s1?isAuthorized=no
