Swell and microstructural characteristics of high-plasticity clay blended with cement (2019)
Journal Article
Abbey, S. J., Eyo, E. U., & Ngambi, S. (2020). Swell and microstructural characteristics of high-plasticity clay blended with cement. Bulletin of Engineering Geology and the Environment, 79, 2119-2130. https://doi.org/10.1007/s10064-019-01621-z

This study presents the effect of high plasticity on swell potential, swelling pressure and micro structural characteristics of kaolinite-bentonite mixed clays. Five different combining ratios of kaolinite bentonite mixture of 100:0, 90:10, 75:25, 50... Read More about Swell and microstructural characteristics of high-plasticity clay blended with cement.

Effect of intrinsic microscopic properties and suction on swell characteristics of compacted expansive clays (2018)
Journal Article
Eyo, E. U., Ng'ambi, S., & Abbey, S. J. (2019). Effect of intrinsic microscopic properties and suction on swell characteristics of compacted expansive clays. Transportation Geotechnics, 18, 124-131. https://doi.org/10.1016/j.trgeo.2018.11.007

© 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... Read More about Effect of intrinsic microscopic properties and suction on swell characteristics of compacted expansive clays.
