为探讨疏浚土壤和转炉炼钢废渣用于滨海环境整治工程的可行性，对疏浚土壤掺入转炉炼钢废渣进行了试验评价。本研究证实，通过水化反应提高了疏浚软土的强度，控制了周围海水的pH值上升，减少了疏浚土中磷的淋洗量。此外，在配合比试验中，确定了f-CaO/W(单位混合料中游离CaO含量与含水率之比)和D-Si/W(可溶硅酸用量与单位混合料中含水率之比)是影响混合料强度的参数。
To investigate the possibility of utilization of dredged soil and converter steel-making slag for coastal environmental improvement works, the experimental evaluation of dredged soil mixed with converter steel-making slag was executed. On this study, the following characteristics about mixture were confirmed that strength of soft dredged soil was improved by hydration reaction, the up of pH value of surrounding seawater were controlled, and the quantity of phosphorus elution from dredged soil was decreased. In addition, in the examination for the mix proportion, it was confirmed that f-CaO/W(ratio of quantity of free-CaO and quantity of water in the unit mixture) and D-Si/W(ratio of quantity of dissolvable silicic acid and quantity of water in the unit mixture) were parameters to influence strength of mixture.
