Solidifying composition for dredged soils including desulfurization slag and quenched blast furnace slag and solidified dredged soils using thereof

摘要

The present invention provides a solidifying composition for dredged soils including desulfurization slag and quenched blast furnace slag, and solidified dredged soils which include 25 to 150 parts by weight of the solidifying composition for dredged soils based on 100 parts by weight of dredged soils and have a compressive strength of 17-36 Mpa 28 days after treatment of the solidifying composition for dredged soils. By using the solidifying composition for dredged soils of the present invention, dredged soils with a low recycling rate are formed into solidified dredged soils with enhanced compressive strength and can be recycled into fill materials or cover materials. Moreover, the solidifying composition can prevent the contamination of soils and fruit trees caused by alkalinization of soils when compared with a solidifying agent using existing cement and Cr^6+ of water and is economical by recycling desulphurization slag and quenched blast furnace slag which are industrial by-products.
