Geri Dönüştürülmüş Cam Kumlu Betonun Mühendislik Özellikleri ve Sürdürülebilirlik Değerlendirmesi

Abstract

Doğal hammadde mevcudiyetindeki azalma, beton endüstrisini çevre dostu yaklaşımlar benimsemeye zorlamaktadır. Beton üretiminde geri dönüştürülmüş malzemelerin kullanılması, beton üretiminin çevresel ayak izini azaltmak için popüler bir yaklaşım haline gelmiştir. Cam, kolayca toplanıp geri dönüştürülebilen en çok tüketilen malzemelerden biridir. Beton üretiminde cam kullanımı, beton üretiminde kullanılan doğal hammadde miktarını potansiyel olarak azaltabilir ve atık gömme icin kullanılan bakir arazilerin depolama amacıyla kullanılmasını önler. Rapor edilen çalışma başlangıçta geri dönüştürülmüş cam kumu kullanılarak üretilen betonun taze ve sertleşmiş performansını araştırmış ve daha sonra da çevresel ve ekonomik sürdürülebilirlik açısından uygunluklarını değerlendirmek için sürdürülebilirlik analizi de yapılmıştır. Bu bağlamda, 30 N/mm2 ve 45 N/mm2 eşdeğer 28 günlük basınç dayanımına sahip kısmen cam kumu ikame (ağırlıkça %10) edilerek yapılan betonlar üretilmiştir. Sonuçlar, geri dönüştürülmüş cam kumu kullanmanın, betonun taze özelliklerini bir miktar iyileştirebileceğini göstermiştir. Geri dönüştürülmüş cam kumunun doğal ince agreganın yerine %10 oranında kullanılmasının, erken yaşlarda basınç dayanımını yaklaşık %10 ve %14 oranında azalttığı gözlenmiştir, ancak basınç kayıplarının 30-RGS ve 45-RGS için normal beton karışımlarına kıyasla sırasıyla 28 günde % 0.6 ve% 10.5'e düştüğü gözlemlenmiştir. Ultrases geçis hızı sonuçları, geri dönüştürülmüş cam kumu kullanımının, normal karışımlara kıyasla benzer veya daha yoğun matris sağladığını gösterdi. Sonuçlar, geri dönüştürülmüş cam kumunun iyi bir agrega değişimi olarak kullanılmasının, 14,4 km'lik bir alanda tedarik edilmesi halinde çevresel olarak sürdürülebilir beton üretimine katkı sağlayabileceğini göstermiştir. Ayrıca geri dönüştürülmüş cam kumu, daha yakın tesislerden tedarik edilmek koşuluyla uygun maliyetli beton üretimi sağlayabildiği de ortaya çıkmıştır.

Engineering Properties and Sustainability Assessment of Recycled Glass Sand Concrete

Abstract

Reduction in the availability of natural raw materials is forcing concrete industry to adopt environmentally friendly approaches. Utilization of recycled materials in concrete production has become a popular approach to lessen the environmental footprint of the concrete production. Glass is one of the most consumed materials that can be easily collected and recycled. Glass use in concrete production may potentially reduce the amount of natural raw materials used in concrete production and prevents the use of virgin lands for landfilling purposes. Reported work initially investigates the fresh and hardened performances of recycled glass sand (RGS) incorporated concrete and further sustainability analysis was also carried out. As an initial attempt for this particular research, natural sand was replaced by 10% RGS in aiming to assess their suitability from the environmental and economical sustainability point of view. In this regard, concretes made with partially substituted RGS (10% by mass replacement) with equivalent 28-day compressive cube strengths of 30 N/mm2 and 45 N/mm2 were produced. The results showed that the use RGS could improve concrete fresh properties slightly. Use of RGS by 10% as a replacement to natural fine aggregate was observed to reduce compressive strength at early ages by approximately 10% and 14% but strength losses were minimized to 0.6% and 10.5% for 30-RGS and 45-RGS respectively at 28-days compared to conventional concrete mixes. Ultrasonic pulse velocity results showed that RGS incorporation provide either similar or denser matrix compared to conventional mixes. Results indicated that use of RGS as a fine aggregate replacement could lead to environmentally sustainable concrete production if it is supplied within range of 14.4 km based on eCO2 emissions. It is also revealed that RGS could provide cost-efficient concrete production on the condition of supplied from closer facilities.
