Description:
Unconfined compression and bound-water content tests were conducted to study the effect of humic acid on the mechanical behaviour of solidified dredged material. It is found that the unconfined compressive strength (qu) and the change in bound-water content (Δmbw) exhibit similar relationships with the humic-acid content and curing time. Both parameters decrease with an increase in humic-acid content until reaching a threshold humic-acid content, above which the magnitudes of both parameters reduce to relatively low and steady values. In addition, both qu and Δmbw increase nonlinearly with the curing time. A relationship between qu and Δmbw is presented; Δmbw may reflect the extent of the hydrates developed in the solidified soil which increases nonlinearly with qu.
