Your recent edits

Hello. In case you didn't know, when you add content to talk pages and Wikipedia pages that have open discussion, you must sign your posts by typing four tildes ( ~~~~ ) at the end of your comment. You may also click on the signature button located above the edit window. This will automatically insert a signature with your username or IP address and the time you posted the comment. This information is useful because other editors will be able to tell who said what, and when. Thank you. --SineBot (talk) 10:55, 24 August 2010 (UTC)[reply]

Cement and Carbon Dioxide

I noticed your contributions to the article on cement and your discussion on the talk page.. In this week's Der Spiegel, a process is described which reduces roughly by half both CO2 emissions and the energy required to make cement. Since my study of chemistry lies decades back, I doubt if I could describe this process adequately for the encyclopedia entry, but apparently researchers at the Karlsruhe Institute for Technology have discovered that even in the traditional process, a temporary intermediate hydrate is produced which, if introduced initially, is responsible for the radical reduction in temperature required (200° in an autoclave) and thus the energy outlay.

The Spiegel article is not available online even in German, but there is a commercial concern with an English website which would have enough information for the sentence or two required in the article. According to the Spiegel article, a manufacturing plant is in the works and a commercial product should hit the market in 2014.

I think this is a significant enough advance in cement manufacturing to warrant a mention in the cement article, but feel that somone with a great deal more expertise in the field than I should do the writing.

Thanks

Hello Janko,

Many thanks for this very interesting information I discover right now, having been in holidays far from the internet these two last weeks. I have quickly browsed to the celitement web site and what I have read there seems to make sense and to be based on solid fundations. The Karlsruhe Institute of Technology (KIT) is a serious research center I know well in another field than cement production. I am not immediately a cement specialist, but I have a great scientific interest for this material as matrix for radioactive waste encapsulation.

If I correctly understand the information provided on the website of Celitement, indeed, everything is based on an intermediate hydrate: celite.

According to the information mentioned here, after hydration, celite forms CSH without producing portlandite (Ca(OH)₂). It means, it is also a low pH cement. Usually, low pH concrete requires addition of pozzolanic materials to the mix of cement and aggregate to transform portlandite into CSH. So celitement could also be used to avoid an alkaline plume in clay and granite formations for deep disposal of radioactive waste where it is crucial to avoid the collapse of bentonite buffers insuring isolation of the waste packages from ground water.

In contrast, the absence of portlandite and the resulting "low pH" would no longer protect the carbon steel rebars from corrosion in surface installations designed to dispose low- and intermediate-level waste.

In the coming weeks, I will try to develop the question of this innovative cementitious materials with low-CO₂ emission. Since several months, I was rather disappointed by commercially-driven green cement papers, often without strong scientific and technical basis. But this information seems me also to be a technical and scientific breaktrough which deserves more attention. Kind regards, Shinkolobwe (talk) 14:37, 24 August 2010 (UTC)[reply]

I didn't notice their calling anything "celite". I just took "celitement" as one of numerous rather unfortunate English neologisms for which Germans are notorious: it's just "cement" with "lite" in the middle and sounds atrocious to a native speaker. Of course the answer to nuclear waste disposal is simply not to produce it in the first place. :) Janko (talk) —Preceding undated comment added 15:12, 24 August 2010 (UTC).[reply]

Celite is also the name of the tricalcium aluminate (C3A) in the Cement chemist notation. I did not notice your explanation of celitement as an English neologism on the web site of celitement. Cheers, Shinkolobwe (talk) 21:09, 24 August 2010 (UTC)[reply]

July 2012 Study of authors of health-related Wikipedia pages

Dear Author/Janko

My name is Nuša Farič and I am a Health Psychology MSc student at the University College London (UCL). I am currently running a quantitative study entitled Who edits health-related Wikipedia pages and why? I am interested in the editorial experience of people who edit health-related Wikipedia pages. I am interested to learn more about the authors of health-related pages on Wikipedia and what motivations they have for doing so. I am currently contacting the authors of randomly selected articles and I noticed that someone at this address edited an article on Influenza. I would like to ask you a few questions about you and your experience of editing the above mentioned article and or other health-related articles. If you would like more information about the project, please visit my user page (http://commons.wikimedia.org/wiki/User:Hydra_Rain) and if interested, please reply via my talk page or e-mail me on nusa.faric.11@ucl.ac.uk. Also, others interested in the study may contact me! If I do not hear back from you I will not contact this account again. Thank you very much in advance.
