Development of a Lytag-silica fume based lightweight concrete and corresponding design equation for pure bending (2023)
Journal Article
Abbey, S. J., Ghassan, N., Booth, C. A., & Nukah, P. D. (in press). Development of a Lytag-silica fume based lightweight concrete and corresponding design equation for pure bending. Case Studies in Construction Materials,

This study presents a novel Lytag-silica fume concrete (LSFC) for structural and other construction applications. The evaluation of compressive strength development and stress strain relationships of the LSFC light weight was carried out to determine...

Optimisation of embodied carbon and compressive strength in low carbon concrete (2022)
Journal Article
Nukah, P. D., Abbey, S. J., Booth, C. A., & Nounu, G. (2022). Optimisation of embodied carbon and compressive strength in low carbon concrete. Materials, 15(23), 8673. https://doi.org/10.3390/ma15238673

To improve the prediction of compressive strength and embodied carbon of low carbon concrete using a program algorithm developed in MATLAB, 84 datasets of concrete mix raw materials were used. The influence of water, silica fume and ground granular b... Read More about Optimisation of embodied carbon and compressive strength in low carbon concrete.

Modelling of quadratic-surface sludge digesters by smoothed particle hydrodynamics (SPH) – Finite element (FE) methods (2020)
Journal Article
Tota-Maharaj, K., Nounu, G., & Ramroop, N. (2020). Modelling of quadratic-surface sludge digesters by smoothed particle hydrodynamics (SPH) – Finite element (FE) methods. Archives of Hydro-Engineering and Environmental Mechanics, 67(1-4), 35-53. https://doi.org/10.1515/heem-2020-0003

The quadric-surfaced sludge digester (QSD), also known as the egg-shaped sludge digester, has proven its advantages over traditional cylindrical digesters recently. A reduction in operational cost is the dominant factor. Its shell can be described as...

Corrugated bamboo as reinforcement in concrete (2017)
Journal Article
Khatib, A., & Nounu, G. (2017). Corrugated bamboo as reinforcement in concrete. Proceedings of the ICE - Structures and Buildings, 170(4), 311-318. https://doi.org/10.1680/jstbu.16.00067

© 2017, Thomas Telford Services Ltd. All rights reserved. This study investigated improving bamboo-concrete bond by increasing mechanical interlock. Pull-out tests were used to measure the bond between bamboo and concrete. Corrugated and non-corrugat... Read More about Corrugated bamboo as reinforcement in concrete.

Utilizing waste recycled glass as sand/cement replacement in concrete (2009)
Journal Article
Taha, B., & Nounu, G. (2009). Utilizing waste recycled glass as sand/cement replacement in concrete. Journal of Materials in Civil Engineering, 21(12), 709-721. https://doi.org/10.1061/%28ASCE%290899-1561%282009%2921%3A12%28709%29

The potential use of waste recycled glass in concrete as recycled glass sand (RGS) and pozzolanic glass powder (PGP) was examined in this study. No major difference was found in compressive strength of concrete with the presence of RGS as sand replac... Read More about Utilizing waste recycled glass as sand/cement replacement in concrete.

Using lithium nitrate and pozzolanic glass powder in concrete as ASR suppressors (2008)
Journal Article

This investigation studies the influence of two different mineral admixtures, lithium nitrate (Li) and pozzolanic glass powder (PGP) on the expansion induced by alkali-silica reaction (ASR). Four numbers of concrete prisms were produced for each conc... Read More about Using lithium nitrate and pozzolanic glass powder in concrete as ASR suppressors.

Properties of concrete contains mixed colour waste recycled glass as sand and cement replacement (2008)
Journal Article
