Fines Content and Cohesion of Lateritic Soils: Conceptual Models | Chapter 01 | Advances in Applied Science and Technology Vol. 5
Laterite has been widely defined as a highly weathered material, rich in secondary oxides of iron, aluminium, or both. It is void or nearly void of basic primary silicates, but it may contain large amounts of quartz and kaolinite. A distinctive feature of laterite and lateritic soils is the higher proportion of sesquioxides of iron and/or aluminium relative to the other chemical components. This study proposed conceptual models for the determination of soil cohesion based on the correlations of soil cohesion with fines content. This was with a view to contributing to timely, less laborious and cost effective determination of cohesion of lateritic soils. Selected lateritic soil samples were subjected to laboratory analyses. The fines were separated from the coarse component of the soils after which the samples were remoulded in varying ratios (fines: coarse) from 10:90 to 100:0 in 10% increment. The samples were ...
