ADDITIVE FOR SOIL GRANULATION AND MODIFICATION METHOD OF SOIL USING THE SAME

摘要

To provide an additive for soil granulation for granulating high moisture containing soil such as construction sludge or soft soil and preparing a soil granulate, easily handling the soil granulate during transportation or reuse, and capable of controlling pH of the soil granulate in a range of 5.8 to 8.6 which are environmental standard values.SOLUTION: There is provided an additive for soil granulation containing a nonionic polymer coagulant having 90% weight cumulative particle diameter of 400 μm or less. Examples of the nonionic polymer coagulant includes a polyacrylamide-based polymer coagulant. The additive for soil granulation can contain an inorganic material such as a calcium carbonate powder, a thickener such as guar gum, or a strength accelerator such as cement.SELECTED DRAWING: None
