Abstract: Solidification technology is an important way for reuse of dredgings; the influence of organic matter on the effect of solidification is a significant problem needs to make clear. Through laboratory study, a remarkable influence of organic matter content on dredging solidification effect was discovered; the relationship of organic matter content and unconfined compressive strength of solidified dredging was made clear; a critical organic matter content 4.3 % exists in dredging, when the organic matter content higher than the content, the adding of organic matter does little influence on solidification effect. According to this principle, a cement-gypsum solidification method is proposed to solidify high organic matter content dredgings.

Key words: organic matter, reuse of dredging, solidification, critical organic matter content
