Special Interview with Journal Author-- Prof. Feng Rao
On March 2, we are delighted to have a special interview with our journal author-- Prof. Feng Rao, from Zijin School of Geology and Mining, Fuzhou University, Fuzhou, Fujian, China.
This interview is initiated on a Research Article from our journal--Influence of Ca on the mechanical properties and microstructures of slag-fly ash geopolymers. This study presents novel insights into the influence of Ca on geopolymerization and in strengthening geopolymer properties. This work evaluates the role of Ca by observing the behavior of hierarchically calciferous geopolymers under different environments, including air, carbonization, and freezing-thawing cycles. The structural and morphological differences between the geopolymers and the related mechanisms in various environmental conditions are assessed based on compressive strength, Brunauer-Emmett-Teller, X-ray diffraction, Fourier transform infrared spectoscopy, nuclear magnetic resonance spectroscopy, and scanning electron microscopy measurements. It is found that two kinds of geopolymer gels, calcium silicate hydrate and sodium aluminosilicate hydrate, are formed in the geopolymerization of blast furnace slag and fly ash. Regardless of the specific air, carbonization, or freezing-thawing cycle environment, the former gel dominates the properties in low Ca geopolymers, while the latter gel determines the properties in medium and high Ca geopolymers. Moreover, the carbonization environment enables calciferous geopolymers with higher surface areas and smaller pore sizes. Such adequate pore structures can significantly improve the performance of the geopolymers.
This interview invites the author to focus on the innovation of this research paper, so as to better bring inspiration to scholars in related research fields. At the same time, under the trend of carbon neutrality in the world, Prof. Rao also states what his team has done in strengthening the resource utilization of mineral and metallurgical solid waste and promoting the green development of the mining and metallurgy industry. Finally, as the Editorial Board member of MMM, Prof. Rao also talked about how Editors should strictly control the quality of articles, which is highly consistent with the editorial department's principle of high-quality publication.
