SOIL MODIFICATION MATERIAL, SOIL MODIFICATION METHOD, MODIFIED SOIL, AND SOIL MODIFICATION TREATMENT METHOD
To provide a soil modification material whose reduction in strength to be expressed can be suppressed even if the material is re-kneaded after a material age has passed.SOLUTION: A soil modification material is mixed with soil to form modified soil, and contains gypsum dihydrate, alumina cement and water absorbent, in which the material contains alumina cement by 5.3 pts.mass or more and 42.9 pts.mass or less and water absorbent by 1.2 pts.mass or more for 100 pts.mass or gypsum dihydrate.SELECTED DRAWING: None
【課題】材齢が経過した後で練り返されても、発現する強度が低下するのを抑制することができる土壌改質材を提供することを課題とする。【解決手段】土壌と混合されて改質土壌を形成する土壌改質材であって、二水石膏と、アルミナセメントと、吸水剤とを含んでおり、二水石膏100質量部に対し、アルミナセメントを5.3質量部以上42.9質量部以下、吸水剤を1.2質量部以上、含む。【選択図】なし
