Kanto loam can be divided into Tachikawa and Musashino loam by the amount of allophane clay mineral. Tachikawa loam has hierarchical ped structure and high specific surface which is caused by the allophane clay mineral. Therefore it needs large amount of quick lime for ground improvement, and requires second chemical additive such as gypsum for , increasing its strength. On the contrary, Musashino loam can react with lesser lime and reach larger strength than Tachikawa loam. The buffer ability of Tachikawa loam for alkaline and acid solution is larger than the other Japanese soils. Therefore, Tachikawa loam can be used for the environmental materials such as buffer materials for alkaline leachate and acid rain.
