materials (cement, lime, fly ash, bitumen or combination of these). The stabilized soil materials havea higher strength, lower permeability and lower compressibility than the native soil (Keller bronchure 32-01E). The method can be achieved in two ways, namely; (1) in situ stabilization and (2) ex-situ stabilization.

The calcium content of the fly ash is perhaps the best indicator of how the fly ash will behave in concrete (Thomas 1999), although other compounds such as the alkalis (Na 2 O and K 2 O), carbon (usually measured as LOI), and sulfate (SO 3) can also affect the performance of the fly ash. Low-calcium fly ashes (< 8% CaO) are invariably
