Effect of intrinsic microscopic properties and suction on swell characteristics of compacted expansive clays

Eyo, E. U.; Ng'ambi, S.; Abbey, S. J.

Abstract

© 2018 Elsevier Ltd The complex swelling mechanism in expansive clays during moisture ingress can be succinctly explained by an examination of their core mineralogy, microfabric, grain size and suction response. This note has attempted to investigate these influential factors on five different expansive clay samples to enable further understanding of swell behaviour. Laser diffractometry tests were performed on the expansive clays to determine the clay-sized particle structure (
