This is mainly related to the constantly emerging challenges, such as not only the development of high-strength concretes is progressing very fast but also the simulation of the flow behaviour is of high importance. The main problem, however, is that the rheological characterisation of fresh concrete is not possible via commercial rheometers. The so-called concrete rheometers provide valuable relative values for comparing different concretes, but they cannot measure absolute values.

The comparison of the ACCR with a commercial rheometer showed very good agreement for selected test materials (Newtonian fluid, shear thinning fluid, suspension, and yield stress fluid), so that self-compacting concrete was subsequently measured. Since these measurements showed a very high reproducibility, the rheological properties of the fresh concrete could be determined with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified Bingham (MB) models) were also tested for their applicability, with the Bingham and the modified Bingham model proving to be the best suitable ones.</jats:p>","lang":"eng"}]},{"date_updated":"2023-04-27T12:33:28Z","publication_status":"published","intvolume":"       422","title":"Flowability of polymer powders at elevated temperatures for additive manufacturing","year":"2023","author":[{"last_name":"Rüther","first_name":"Moritz Johannes","full_name":"Rüther, Moritz Johannes","id":"38188"},{"full_name":"Klippstein, Sven Helge","last_name":"Klippstein","first_name":"Sven Helge","id":"71545"},{"last_name":"Ponusamy","first_name":"SathishKumar","full_name":"Ponusamy, SathishKumar","id":"77383"},{"last_name":"Rüther","first_name":"Torben","full_name":"Rüther, Torben","id":"76950"},{"id":"464","full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim","orcid":"000-0001-8590-1921","last_name":"Schmid"}],"publication_identifier":{"issn":["0032-5910"]},"doi":"10.1016/j.powtec.2023.118460","article_number":"118460","language":[{"iso":"eng"}],"publication":"Powder Technology","keyword":["General Chemical Engineering"],"type":"journal_article","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"date_created":"2023-03-27T19:57:12Z","status":"public","user_id":"71545","volume":422,"_id":"43128","publisher":"Elsevier BV","quality_controlled":"1","citation":{"short":"M.J.

This has already been investigated intensively by various authors. However, the ageing of the material at ambient temperatures during shelf life has not been the focus so far. The need to analyse the shelf life can be derived from an ecological and economic point of view. This work is focusing on the shelf life of PA2200 (PA12). To reduce the potential influences of powder production fluctuations, two different powder batches stored for 5.5 years and 6.5 years are investigated and compared to a reference powder produced 0.5 years before these investigations. Multiple powder analyses and part characterisations have been performed. A significant yellowing and molecular chain length reduction can be derived from the measurement results. Whereas the influence on mechanical part performance was minor, the parts built with the stored powders are more yellowish. As it is most likely that this is due to the consumption of polyamide stabilisers, it can be assumed that these parts will be subject to significantly faster ageing. Therefore, it is still not recommended to use the stored powders for critical parts or light intense and humid environments.","lang":"eng"}],"publication":"The International Journal of Advanced Manufacturing Technology ","user_id":"50769","publisher":"Springer","_id":"43046","status":"public","oa":"1","quality_controlled":"1","citation":{"ieee":"S.
