Description

The purpose of this study is to clarify the relationship between the degree of weathering and the content of amorphous materials and the influence of amorphous components on the lime stabilization of the soil from the physico-chemical point of view.<br>The ignition loss and the specific surface area which have been adopted as a criterion of the degree of weathering are related closely to the ratio of Al2O3/SiO2. This fact means that the ratio can be also used as a criterion of the degree of weathering from the chemical point of view.<br>In conclusion, the ratio of Al2O3/SiO2 and lime content have a decisive effect on the unconfined compressive strength of the sample stabilized with lime.
