    Characterisation of Cement Loaded With Magnetically Aligned Nano-Magnetite
    (ICE Publishing, 2023) Jassam, T.M.; Lau, B.; Yang-Zhi, J.N.; Kien-Woh, K.; Al-Mansob, R.A.; Erdil, B.; Luo, W.
    In this study, the effect on the compressive strength of cement with the addition of 1-5 wt% nano-magnetite particles (nano-Fe3O4) is identified at the age of 7 days and 28 days of curing. In addition, an approach of aligning these nano-magnetite particles within cement using an external magnetic field is presented, where the orientation of nano-magnetite particles is aligned parallel to the compressive load. The effect of the compressive strength on cement mortar with the aligned nano-magnetite particles is compared with the non-aligned samples. Both aligned and non-aligned samples show positive effects on the compressive strengths as compared to the control samples, where the cement mortar with aligned nano-magnetite shows significant improvement on compressive strength up to 21%. This study also shows that the addition of 3 wt% nano-magnetite particles to cement mortar is the optimal amount to achieve maximum enhancement of compressive strengths. © 2023 Emerald Publishing Limited: All rights reserved.
