PROBLEM TO BE SOLVED: To provide a solidification material of sludge and a processing method of the sludge using the same by which various kinds of sludge of high water content and of being hard to handle such as construction sludge, dredged sludge of a river, a port or the like, water purifying plant sludge and factory waste water sludge can be solidified by a low-priced hydraulic solidification material effectively using industrial waste or the like discharged or recovered from various kinds of industries, the solidified material is not sludged again and can be recycled and reused as a formed material that is mild to environment and is easy to handle. SOLUTION: An inorganic solidification material for sludge can solidify various kinds of sludge of high water content to a shape of being easy to handle and further can process the sludge to the solidified material of a granule-shape or the like capable of preventing from being sludged again. In this powdery hydraulic inorganic solidification material of low price, a powdery high molecular flocculant is effectively used to industrial discharge discharged and recovered from various kinds of industries such as the hydraulic solidification material and an inorganic water-absorptive hardening accelerator.
