Title:

LOW ALKALI SOLIDIFYING MATERIAL

Document Type and Number:

Japanese Patent JPH10225669

Kind Code:

A

Abstract:

To effectively utilize a large quantity of fly ash and molten slag to restrain the quantity of cement used by making contain cement, fly ash and slag powder to prepare low alkali solidifying material for subjecting to solidifying treatment sludge or the like generated in civil work or dredge work.

This low alkali solidifying material is that which contains cement, fly ash and slag powder, and in order to decrease an elution pH value immediately after mixing with soft mud, the quantity of the cement is made small, for example, the quantity of the cement is within a range of 15-30 pts.wt., and mixing is performed in the ratio of 40-60 pts.wt. fly ash to 20-35 pts.wt. slag powder. As the cement, various kinds of Portland cement such as high- early-strength and moderate-heat Portland cement are used. The high-early- strength Portland cement excels in providing strength and is suitably used. As the slag powder, molten slag powder made using various kinds of waste such as blast furnace slag, trash incineration products an industrial waste as raw materials is suitably used.
