Abstract

The specific surface area is an important property in assessing the physical interaction of clay particles with additives. In this paper, the time-dependent changes induced in surface area of phosphoric acid treated tropical soils comprised mainly of kaolinite mineral were investigated. Comparison between the BET results indicated that the effects of acidic stabilizer on the surface area of soil particles were significant. Furthermore, it was found that the presence of free iron oxides in the form of micro-aggregates on the surface of soil particles contributed to achieving higher surface area values while limiting the attack of phosphoric acid on the clay particles.
