The research presented in this thesis can be split into two well-defined areas. Firstly, the effects of the addition of lime (either 2%, 4%, 6% or 8% Ca(OH)2 or 1.5%, 3%, 4.5% or 6% CaO) on various engineering properties of a sulphide (pyrites) rich, naturally occurring clay - L…

The main objective of this thesis is to investigate the impact of microbial extracellular polymeric substances (EPS) on sediment stability and the related factors which influence “biogenic stabilisation” as a basis to the prediction of sediment erosion and transport. The ability…

The effects of biological and physical processes on the aggregate stability of some weakly structured arable and pasture soils were investigated. Preliminary investigations showed significant correlations between soil organic matter and both wet sieving and turbidimetric methods…

In this research study, an attempt is made to address limitations in soil stabilization. Incorporation of the clay mineralogy aspects of the soils into the stabilization design process was first addressed, followed by durability studies to address the long-term effectiveness of …
