Role of Iron Oxides in the Bonding of Soil Particles

Abstract

THE presence of significant amounts of iron oxides in soils is generally considered to exert important effects on their physical properties, but no satisfactory experimental evidence exists to substantiate this view. A series of experiments has therefore been carried out to determine what effect the removal of iron oxides from natural aggregates has on their stability. In addition attempts have been made to improve the aggregation of soils by precipitation of iron and aluminium oxides on the soil particles.
