Kaunisbetoni

Betonia käytetään paljon sen kestävyyden, kätevyyden ja taloudellisuuden takia eikä siinä mitään. Siisti, tasaisen vaalea betonipinta on myös varsin esteettinen. Vanhetessaan se alkaa kuitenkin usein tummentua, läikittyä ja harmaantua saaden minkä tahansa espoolaisen parkkipaikan näyttämään romanialaiselta ratapihalta marraskuussa.

Nyt tarvittaisiin esteettisen materiaalitekniikan asiantuntijaa: kuinka paljon ja millaisia lisäaineita betonimassaan voisi lisätä siten, että väri pysyisi tasaisena tai vanhenisi kauniista heikentämättä kuitenkaan betonin kestävyyttä? Voisiko massaan lisätä esimerkiksi hienoa rautapölyä, joka ruostuessaan värjäisi betonin? Väri vaihtuisi pinnan vanhetessa, mutta kauniisti.

    Concrete technology has been around for some time now, I guess the answer to the question of grarceful degradation has been sought after for quite a while. Since concrete is not like the naturally occuring rocks, it has the tendency to deteriorate quickly(Not too quickly, it is long lasting but not very much when compared to some metamorphic rocks). Maybe the answer to the question will be found in an alternate composite, perhaps polymer scientists will be able to invent something to assist it or replace it.

    Wow, Anoop, my Christian friend from India!

    Google translator doesn’t do very good job with Finnish these days (“Could the increase in its example of fine iron dust, which ruostuessaan värjäisi concrete?”😛 ) but you certainly got the point.

    I’m wondering if we as grownups learn aesthetic views. Could we accept that an old concrete house is a beautiful one?

    btw. I like the idea of designing the process of building material getting older in a specific way. Rust is used for this pretty often (especially in copper roofs in Helsinki) but that is the only method which is used that comes to my mind.

    Yes you are right Google translator is probably not a very good tool, but I’m sure that over time it will improve. I read some where that they are developing a serial translator, that will record what you are saying and then translate it one sentence at a time, right it is only for a few languages, but they might be able to add more soon.

    Old houses ARE beautiful!!! But old office building are not :)….These things are programmed in our head since childhood, like the first time we heard our parents say, “That looks so ugly.”…….But maybe somethings are beautiful because of symmetry and balance, because out of every possible thing in the world, only a few exist, i.e., out of the letters b,d,a only the words ad, ab, bad and dab exist, while bd,db,dba etc don’t. So these words are not beautiful or important to us, similarly with buildings, the building designs that make sense, i.e, have some symmetry and have contrasting colours etc.

    The light transmitting concrete is pretty cool, if they could put more fibres then maybe they can make it invisible and create invisible walls, or if they used fibres that have attenuation in one direction and can transmit in the other, then they can have a sort of looking window like in police questioning rooms, without having to worry about getting hurt.

    read this about the random words thing(If you don’t alread know), its pretty cool… http://en.wikipedia.org/wiki/The_Library_of_Babel
