POWDER SOLIDIFYING MATERIAL FOR SOFT MUD SOIL AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive powder solidifying material for soft mud soil which is a cement-free non-cement-based powder solidifying material for the soft mud soil having high coagulation performances and effectively solidifying the soft mud soil and to provide a method for producing the powder solidifying material for the soft mud soil.

SOLUTION: The powder solidifying material for the soft mud soil is produced as follows: Papermaking sludge incineration ash and/or organic incineration ash as a main raw material is compounded with clinker ash and anhydrous gypsum as a solidification aid and an inorganic coagulant, cationic polymer coagulant powder and anionic polymer coagulant powder as a coagulant.
