Abstract

Bu çalışma, 24 Ocak 2020 Elazığ-Sivrice depremi sonrasında kontrollü bir şekilde yıkılan binalardan
ortaya çıkan geri dönüştürülmüş beton agregaları kullanılarak üretilen geri dönüşüm iri agregalı
betonların (GDİAB) ve doğal agregalı betonların (DAB) çevresel etki sonuçlarını karşılaştırmayı
amaçlamaktadır. Bu amaçla 12 farklı beton serisi üretilmiş ve çevresel etki değerlendirmeleri
karşılaştırılmıştır. Karşılaştırmalar yapılırken çevresel etki kategorilerinden Enerji Tüketimi, Küresel
Isınma Potansiyeli, Atık Üretimi ve Abiyotik Tükenme ele alınmıştır. Üretilen betonların çevresel etki
karşılaştırmalarını yapabilmek için dört farklı senaryo geliştirilmiştir. Senaryolar incelendiğinde geri
dönüşümlü beton agregaların kullanımının büyük çevresel faydalar sağladığı görülmüştür. Deprem
sonrası ortaya çıkan milyonlarca ton atık malzeme ve yeni inşa edilen binalar göz önüne alındığında, atık
malzemelerin geri dönüştürülmesinin büyük önem taşıdığı bir kez daha ortaya çıkmıştır.

Environmental Impact Assessment of Recycled Aggregate Concretes

Abstract

This study aims to compare the environmental impact results of recycled coarse aggregate concrete
(RCAC) produced using recycled concrete aggregates (RCA) that emerged the demolished buildings in a
controlled manner after January 24, 2020, Elazig-Sivrice earthquake, recycled coarse aggregate
concrete (RCAC), and natural aggregate concrete (NAC). For this purpose, 12 different concrete series
were produced, and their environmental impact assessments were compared. While making
comparisons, Energy Consumption, Global Warming Potential, Waste Generation, and Abiotic
Depletion, which are environmental impact categories, were discussed. Four different scenarios were
developed to make environmental impact comparisons of the produced concretes. When the scenarios
were examined, it was seen that the use of recycled concrete aggregate provides great environmental
benefits. Considering the millions of tons of waste materials and newly constructed buildings that
emerged after the earthquake, it has once again emerged that recycling waste materials is of great
importance.
