Incorporation of a nanotechnology-based product in cementitious binders for sustainable mitigation of sulphate-induced heaving of stabilised soils (2020)
Journal Article
Eyo, E. U., Abbey, S. J., Ngambi, S., Ganjian, E., & Coakley, E. (2021). Incorporation of a nanotechnology-based product in cementitious binders for sustainable mitigation of sulphate-induced heaving of stabilised soils. International Journal of Engineering Science and Technology, 24(2), 436-448. https://doi.org/10.1016/j.jestch.2020.09.002

Sulphate-induced heaving in soils is a common problem caused mostly by the use of calcium-based binders in the stabilisation of sulphate-bearing soils. Sulphate-induced heaving is attributed to precipitation and growth of ettringite minerals in a hig...

An overview of soil–water characteristic curves of stabilised soils and their influential factors (2020)
Journal Article
Eyo, E. U., Ng'ambi, S., & Abbey, S. (2022). An overview of soil–water characteristic curves of stabilised soils and their influential factors. Journal of King Saud University (Engineering Science), 34(1), 31-45. https://doi.org/10.1016/j.jksues.2020.07.013

Since unsaturated soil conditions are normally experienced above the groundwater table, most treated or stabilised soils for roadworks, earth dams’ embankments, landfill sites, hydraulic barriers etc. could be regarded as existing in this region. The... Read More about An overview of soil–water characteristic curves of stabilised soils and their influential factors.

Incorporation of a nanotechnology-based additive in cementitious products for clay stabilisation (2020)
Journal Article
Eyo, E. U., Ng'ambi, S., & Abbey, S. J. (2020). Incorporation of a nanotechnology-based additive in cementitious products for clay stabilisation. Journal of Rock Mechanics and Geotechnical Engineering, 12(5), 1056-1069. https://doi.org/10.1016/j.jrmge.2019.12.018

The mechanical performances and water retention characteristics of clays, stabilised by partial substitution of cement with by-products and inclusion of a nanotechnology-based additive called RoadCem (RC), are studied in this research. The unconfined... Read More about Incorporation of a nanotechnology-based additive in cementitious products for clay stabilisation.

Mechanical properties and microstructure of fibre-reinforced clay blended with by-product cementitious materials (2020)
Journal Article
Abbey, S. J., Eyo, E. U., Oti, J., Amakye, S. Y., & Ngambi, S. (2020). Mechanical properties and microstructure of fibre-reinforced clay blended with by-product cementitious materials. Geosciences, 10(6), 241. https://doi.org/10.3390/geosciences10060241

Clayey soils endure adverse changes in strength and volume due to seasonal changes in moisture content and temperature. It has been well recognised that high cement content has been successfully employed in improving the mechanical properties of clay...
