ppt on laterite soil on emaze
The soil Laterite rich in aluminum are termed aluminous laterite or bauxite. Aluminous laterite is formed from clay minerals such as kaolinite (Al4 [Si4O10] [OH]8) by the leaching of silica (SiO2). The residue left by the leaching of silica, aluminum hydroxide (Al [OH]3), is termed gibbsite. Gibbsite's dehydrated forms, diaspore and bohemite ...

Home An Introduction in Laterite
An Introduction to Laterite . Products and processes of intensive rock weathering. W. Schellmann. Historical development. Laterite is well known in Asian countries as a building material for more than 1000 years. It was excavated from the soil and cut in form of large blocks; temples at Angkor are famous examples for this early use.
