Characterization of cement loaded with magnetically aligned nano-magnetite
In this study, the effect on the compressive strength of cement with the addition of 1-5 wt% nano-magnetite particles (nano-Fe 3 O 4 ) has been identified at the age of 7 days and 28 days curing. In addition, an approach of aligning these nano-magnetite particles within cement using an external magnetic field was presented, where the orientation of nano-magnetite particles was aligned parallel to the compressive load. The effect of the compressive strength on cement mortar with the aligned nano-magnetite particles has also been compared with the non-aligned samples. Both aligned and non-aligned samples showed positive effects on the compressive strengths as compared to the control samples, where the cement mortar with aligned nano-magnetite showed significant improvement on compressive strength up to 21%. This study also showed that the addition of 3 wt% nano-magnetite particles into cement mortar was the optimal amount to achieve maximum enhancement of compressive strengths.
