摘要

在本研究中，研究了在龄期7天和养护28天时，添加1-5 wt%的纳米磁铁矿颗粒(纳米fe3o4)对水泥抗压强度的影响。此外，提出了一种利用外部磁场在水泥中对齐这些纳米磁铁矿颗粒的方法，其中纳米磁铁矿颗粒的方向与压缩载荷平行。对比了纳米磁铁矿排列后对水泥砂浆抗压强度的影响。与对照样品相比，排列和未排列的样品对抗压强度都有积极的影响，其中纳米磁铁矿排列的水泥砂浆的抗压强度显著提高了21%。该研究还表明，在水泥砂浆中添加3wt %的纳米磁铁矿颗粒是获得最大抗压强度增强的最佳量。

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.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
