SOIL GRANULATING ADDITIVE
PROBLEM TO BE SOLVED: To provide a soil granulating additive capable of improving a strength of soil (such as cone index), making it difficult for the soil after solidification to become lumpy, making it easy to select unnecessary waste such as vegetation or rocks from the soil by using a filter, further, making the pH of the soil near, for example, such as rendering to the range of 5.8 to 8.6 that is an effluent standard.SOLUTION: A soil granulating additive includes: 100 parts by mass of inorganic powder; and 0.01 to 50 parts by mass of a thickening material. The inorganic powder has preferably a Blaine specific surface area of 1500 g/cmor larger and is one kind selected from calcium carbonate powder, gypsum hemihydrate, anhydrous gypsum, bentonite, zeolite, silica powder, coal ash, shale powder, sepiolite, activated carbon, activated clay, diatom earth, and dolomite.SELECTED DRAWING: None
【課題】土壌の強度（例えば、コーン指数）を向上することができ、かつ、固化処理後の土壌が塊状となりにくく、ふるい等を用いて、土壌から草木、岩石等の不要な廃棄物を選別することが容易となり、さらには、土壌のｐＨを、例えば、排水基準値である５．８〜８．６の範囲内に収めるなど、中性に近づけることができる土壌造粒用添加材を提供する。【解決手段】無機粉末１００質量部、および増粘用材料０．０１〜５０質量部を含む土壌造粒用添加材。上記無機粉末は、好ましくはブレーン比表面積が１５００ｇ／ｃｍ２以上で、かつ、炭酸カルシウム粉末、半水石膏、無水石膏、ベントナイト、ゼオライト、珪石粉末、石炭灰、頁岩粉末、セピオライト、活性炭、活性白土、珪藻土、およびドロマイトの中から選ばれる１種以上である。【選択図】なし
