Effect of P2O5 and chloride on clinkering reaction
Korean ceramics researchers have recently investigated the potential for using sewerage sludge in cement production. Their research looks at the possibility of effective reutilization of sewage sludge into cement kiln processes. They describe their findings in the online materials science journal AZojomo*.
Increasing environmental regulations on marine dumping means new disposal methods must be found for sewerage sludge. The use of sewage sludge as a raw material for the production of cement is an effective method, since the organic components may serve as fuel while the inorganic components such as SiO2, Al2O3, Fe2O3 components offer as the raw material for the clinker. However, one of the obstacles to this application to cement kilns is the relatively high P2O5 and Cl content in sewage sludge.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
