Dr. \u00d6\u011fretim \u00dcyesi Yusuf \u00c7a\u011fatay Er\u015fan, 2013-2016 y\u0131llar\u0131 aras\u0131nda Bel\u00e7ika Ghent \u00dcniversitesinde bir grup akademisyenle birlikte yapt\u0131\u011f\u0131 doktora \u00e7al\u0131\u015fmas\u0131nda, beton kar\u0131\u015f\u0131m\u0131n\u0131n i\u00e7erisine bakteri ekleyerek, kendi kendini yenileyen daha uzun \u00f6m\u00fcrl\u00fc bir beton elde etmeyi ba\u015fard\u0131. \u2018Biyobeton\u2019 ad\u0131 verilen \u00e7al\u0131\u015fmada, \u00e7e\u015fitli i\u015flemlerden ge\u00e7irilerek beton kar\u0131\u015f\u0131m\u0131n\u0131n i\u00e7erisine eklenen bakteriler, betonlardaki \u00e7atlaklar\u0131 kire\u00e7 ta\u015f\u0131 ile doldurarak, tamir gereksinimini ortadan kald\u0131r\u0131yor ve betonun \u00f6mr\u00fcn\u00fc uzat\u0131yor. Ayr\u0131ca biyobeton sayesinde beton i\u00e7erisindeki \u00e7elik donat\u0131lar\u0131n korozyona u\u011framas\u0131n\u0131n \u00f6n\u00fcne ge\u00e7iliyor, b\u00f6ylece betonun \u00f6mr\u00fc uzat\u0131lm\u0131\u015f oluyor.<\/p>\n
Betonun i\u00e7erisine ilave edilen bakteriler \u00e7atlaklar\u0131 onar\u0131yor<\/p>\n
\u2018Biyobeton\u2019u daha optimum bir kar\u0131\u015f\u0131m elde etmek i\u00e7in \u00e7al\u0131\u015fmaya devam ettiklerini s\u00f6yleyen Er\u015fan, betonun kendi kendini onarma s\u00fcreci hakk\u0131nda \u015fu bilgileri verdi:<\/p>\n
\u201cNormal bir betonda kum, \u00e7imento ve agregalar vard\u0131r. Biyobetonda ise bunlar\u0131n yan\u0131 s\u0131ra gerekti\u011finde betonu tamir edebilecek bakteriler bulunuyor. Bakterileri kum gibi, kurutulmu\u015f toz \u015feklinde beton kar\u0131\u015f\u0131m\u0131n\u0131n i\u00e7erisine entegre ediyoruz. Beton sertle\u015ftikten sonra olu\u015fabilecek hem erken ya\u015f hem de ileriki d\u00f6nemlerde olu\u015fabilecek \u00e7atlaklara kar\u015f\u0131 betona bir nevi a\u015f\u0131 yapm\u0131\u015f oluyoruz. Bakterileri betonun i\u00e7erisine spor halde yerle\u015ftirdi\u011fimiz i\u00e7in, bakteriler beton \u00e7atlayana ve herhangi bir su s\u0131z\u0131nt\u0131s\u0131yla kar\u015f\u0131 kar\u015f\u0131ya kalana kadar uyku modundalar. Ama beton \u00e7atlad\u0131\u011f\u0131 andan itibaren i\u00e7eri giren su ve \u00e7\u00f6z\u00fcnen besinlerle birlikte ortam bakterilerin harekete ge\u00e7mesi i\u00e7in uygun hale geliyor ve bakteriler kalsiyum karbonat \u00e7\u00f6kmesini sa\u011flayarak \u00e7atlaklar\u0131 kapat\u0131yorlar.\u201d<\/p>\n
Suyla temas eden beton yap\u0131larda kullan\u0131l\u0131yor<\/p>\n
Biyobetonun suyla temas eden k\u00f6pr\u00fc ayaklar\u0131, limanlar, denizalt\u0131 t\u00fcnelleri, yatay oldu\u011fu i\u00e7in su tutan yollar gibi yap\u0131larda kullan\u0131labilece\u011fini belirten Er\u015fan, \u00fcr\u00fcn\u00fcn ayn\u0131 zamanda bu gibi yap\u0131larda kullan\u0131lan \u00e7elik donat\u0131lar\u0131 da korozyona kar\u015f\u0131 korudu\u011funu ifade etti. Bu \u015fekilde betonun \u00f6mr\u00fcn\u00fc uzatt\u0131klar\u0131n\u0131 dile getiren Er\u015fan, \u201c\u00c7al\u0131\u015fmada kulland\u0131\u011f\u0131m\u0131z biyogran\u00fcller \u00e7elik korozyonunu da engelliyor. Yani hem \u00e7atla\u011f\u0131 onar\u0131yor hem de \u00e7eli\u011fin \u00fczerinde koruyucu bir tabaka olu\u015fturarak, \u00e7eli\u011fi de uzun s\u00fcre koruyabiliyor\u201d dedi.<\/p>\n
Betonun \u00f6mr\u00fc uzuyor<\/p>\n
Halihaz\u0131rda biyobetonun ba\u015flang\u0131\u00e7 maliyetleri y\u00fcksek olsa da, sonradan ortaya \u00e7\u0131kan i\u015fletme ve tamir masraflar\u0131n\u0131 ortadan kald\u0131rd\u0131\u011f\u0131 i\u00e7in uzun vadede karl\u0131 oldu\u011funu vurgulayan Er\u015fan, \u201c\u00c7al\u0131\u015fmaya ba\u015flad\u0131\u011f\u0131m\u0131z 2013 y\u0131l\u0131nda y\u00fczde bin-2 bin civar\u0131nda ba\u015flang\u0131\u00e7 maliyetleri konu\u015fulurken \u015fu andaki \u00e7al\u0131\u015fmalar\u0131m\u0131zla bu maliyeti on kat\u0131na kadar d\u00fc\u015f\u00fcrd\u00fck. Ancak piyasa ko\u015fullar\u0131 i\u00e7in halen bu d\u00fczey yeterli de\u011fil. Fakat kurtard\u0131\u011f\u0131 maliyetler bak\u0131m\u0131ndan avantajl\u0131. \u00c7\u00fcnk\u00fc betonu s\u00fcrekli takip etmek zorunda kalm\u0131yorsunuz ve \u00e7atlak olu\u015ftu\u011funda tamir etmek i\u00e7in ekstra masraflar\u0131n\u0131z olmuyor. Tamirat s\u0131ras\u0131nda bir yolu, t\u00fcneli, k\u00f6pr\u00fcy\u00fc kapatmak \u00e7ok ciddi maliyetler ve hizmet aksamalar\u0131na neden oluyor, ancak biyobeton kullan\u0131ld\u0131\u011f\u0131nda t\u00fcm bu maliyetler ortadan kalk\u0131yor. Ayr\u0131ca betonun \u00f6mr\u00fcn\u00fc uzatarak maliyetlerin azalt\u0131lmas\u0131na ikinci kez katk\u0131 sunulmu\u015f oluyor. Yani halihaz\u0131rda ba\u015flang\u0131\u00e7 maliyetleri y\u00fcksek olsa da, ileri a\u015famalarda ortaya \u00e7\u0131kabilecek i\u015fletme maliyetlerinin \u00f6n\u00fcne ge\u00e7mi\u015f oluyoruz\u201d ifadelerini kulland\u0131.<\/p>\n","protected":false},"excerpt":{"rendered":"
