Abstract

This paper examines the compression and strength characteristics of soils in relation to the presence of isolated solid inclusions such as colluvium and glacial till. Investigations were carried out on samples of kaolin with solid inclusions of angular crushed basalt and steel ball bearings (to represent rounded particles). It was observed that the presence of solid inclusions has a significant effect on the compression and strength characteristics of these composite soils and it is postulated that this behaviour is related to the formation of strong arches between the individual solid inclusions. This phenomenon was found to be subdued when the surface of the solid inclusion is smooth, suggesting that particle shape has also considerable influence on the mechanical behaviour of composite materials.
