Ara\u015ft\u0131rmac\u0131lar bile\u015fenleri aras\u0131nda in\u015faat at\u0131klar\u0131 ve CO2 bulunan daha ye\u015fil bir tu\u011fla<\/strong> yapman\u0131n yolunu buldu. <\/figure>\n

Y\u0131k\u0131lan binalar ve CO2 kullan\u0131l\u0131yor<\/b><\/p>\n

Ara\u015ft\u0131rmac\u0131lar\u0131n ilk kez 2021 y\u0131l\u0131nda ortaya koyduklar\u0131 ve zamanla \u00fczerinde ciddi geli\u015ftirmeler uygulad\u0131klar\u0131 bir y\u00f6ntem in\u015faat end\u00fcstrisini biraz daha ye\u015fil tarafa kayd\u0131rabilir. S\u00f6yledi\u011fimiz gibi beton \u00fcretiminin b\u00fcy\u00fck bir \u00e7evresel maliyeti var. Bunun b\u00fcy\u00fck bir k\u0131sm\u0131, portland \u00e7imentosunun<\/strong> temel bile\u015fenlerinden biri olan kire\u00e7ta\u015f\u0131n\u0131<\/strong> \u0131s\u0131tarak kalsiyum<\/strong> elde etmek i\u00e7in gereken y\u00fcksek s\u0131cakl\u0131klardan<\/strong> kaynaklan\u0131yor.<\/p>\n

Japon ara\u015ft\u0131rmac\u0131lar bu s\u00fcreci kullanmak yerine kendi y\u00f6ntemleriyle kalsiyum karbonat beton<\/strong> ad\u0131 verilen bir yap\u0131 malzemesi olu\u015fturuyor. Bunu ise zaten mevcut olan betonu, molozlar\u0131 veya y\u0131k\u0131lan binalar\u0131<\/strong> havadan veya end\u00fcstriyel s\u00fcre\u00e7lerden al\u0131nan karbondioksit ile birle\u015ftirerek<\/strong> ger\u00e7ekle\u015ftiriyorlar. \u0130lk ba\u015flarda \u00fcretilen beton bloklar, daha do\u011frusu tu\u011flalar olduk\u00e7a k\u00fc\u00e7\u00fck ve dayan\u0131ks\u0131zd\u0131.<\/p>\n

<\/span> \u015eimdi ara\u015ft\u0131rmac\u0131lar y\u0131k\u0131lm\u0131\u015f bir okul binas\u0131ndan beton alarak ince bir toz haline getirdiler ve ard\u0131ndan \u00fc\u00e7 ayl\u0131k bir s\u00fcre<\/strong> boyunca havadan al\u0131nan CO2 ile kar\u0131\u015ft\u0131rd\u0131lar<\/strong>. Bu karbonatl\u0131 toz daha sonra bir kalsiyum bikarbonat \u00e7\u00f6zeltisi<\/strong> ile bas\u0131n\u00e7land\u0131r\u0131ld\u0131. Ortaya konan tu\u011flan\u0131n ise normal evler ve kald\u0131r\u0131mlar in\u015fa etmek i\u00e7in yeterince b\u00fcy\u00fck ve g\u00fc\u00e7l\u00fc<\/strong> oldu\u011fu bildirildi. <\/figure>\n

Yeni y\u00f6ntem sadece eski binalar\u0131 yeni binalar yaratmak i\u00e7in kullanmakla kalm\u0131yor, ayn\u0131 zamanda kalsiyum karbonat beton tu\u011flalar\u0131n kendileri de yap\u0131 \u00f6m\u00fcrlerinin sonunda toz haline getirilebiliyor ve yeni in\u015faatlar i\u00e7in yap\u0131 ta\u015flar\u0131 olu\u015fturmak \u00fczere s\u00fcre\u00e7 tekrarlanabiliyor. Ekibin Kalsiyum Karbonat Sirk\u00fclasyon Sistemi (C4S) bir sonraki a\u015famada verimlili\u011fi art\u0131rmaya ve pilot \u00fcretim tesisine odaklanacak<\/strong>. Ekip ayr\u0131ca 2030 y\u0131l\u0131na kadar kalsiyum karbonat beton tu\u011flalar\u0131 kullanarak iki katl\u0131 bir ev in\u015fa etmeyi hedefliyor. Elbette ekibin ortaya koydu\u011fu y\u00f6ntemi her yerde kullanmak mant\u0131kl\u0131 ve m\u00fcmk\u00fcn de\u011fil. Ancak Japonya gibi kire\u00e7ta\u015f\u0131 a\u00e7\u0131s\u0131ndan k\u0131s\u0131r olan \u00fclkelerde bu y\u00f6ntem kullan\u0131labilir.<\/p>\n\n
