During carbon steel manufacture, slag residues are generated to remove material impurities from liquid metal and thus control the quality of carbon steel. As the utilization of secondary metallurgical slags is not as efficient as those of primary slags, a comprehensive characterization of steel ladle slag was performed. Pseudo-total concentrations of a wide range of elements were determined dur...

The discovery of the extreme antiquity of specific minerals through radiometric dating (e.g., Strutt 1910), coupled with Norman L. Bowen’s recognition of a deterministic evolutionary sequence of silicate minerals in igneous rocks (Bowen 1915, 1928), implies that Earth’s crustal mineralogy has changed dramatically through more than 4.5 billion years of planetary history. Detailed examination of ...

The paper presents and analyzes the mineralogical, physical and chemical composition of dust deposited samples at six sites on the KAUST campus. KAUST is located on the Red sea coastal plain of Saudi Arabia. Monthly samples were collected between December 2014 and December 2015. The monthly deposition trends were compared to visibility and sun photometric measurements and to previous mineralogi...

Alkali-activated materials (AAM) and hybrid cements (HC) have become sustainable alternatives to Portland cement (PC) due their low carbon footprint. The main differences between AAM HC lie in content of clinker (none the usually lower than 30% for HCs) type activator used (strong alkaline solutions small amounts solid alkalis HC). Durability problems related with microstructural changes decalc...

Raman microspectroscopy measurements were performed on Hayabusa sample RA-QD02-0197. The sample has been provided by JAXA to our consortium in the scope of the 1 International Announcement of Opportunity [1]. Raman microspectroscopy is an appropriate technique for a contactless mineralogical investigation and is applied to describe the mineralogical composition of the sample. For the noble gas ...
