Özet
Her yıl yüz milyonlarca araç lastiği servis süresini doldurması nedeniyle atık olarak ortaya çıkmakta, bu durum sağlık ve çevre açısından küresel sorunlara neden olmaktadır. Günümüzde doğal inşaat kumunun az bulunan ve daha maliyetli bir malzeme haline gelmesi, doğal kuma göre daha ekonomik, sürdürülebilir olması beton teknolojisinde ince agrega olarak kullanımının yolunu açmıştır. Bu çalışmada, atık lastiklerden elde edilen kauçuk granül agrega (CRA), beton karışım dizaynında ince agreganın 1-2 mm elek aralığında kalan miktarına ağırlıkça %0 (Kontrol), %5, %10 ve %15 oranlarında ikame edilmiş ve numunelerin mekanik ve morfolojik özellikleri araştırılmıştır. Bu amaçla beton numunelerinin; birim ağırlık, su emme, 3, 7 ve 28 günlük basınç dayanımları, donma-çözünme (100 çevrim) ve ultrases deneyleri yapılmıştır. Ayrıca, numunelerin SEM (ScanningElectronMicroscope) görüntüleri ve EDS spektrum analizleri incelenmiştir. Çalışmanın sonucunda, %5 oranında CRA içeren numunenin diğer numunelere göre dahauygun sonuçlar verdiği belirlenmiştir.
Every year hundreds of millions of tyres come out as waste because they fill their service period and this situation causes global problems in respect of health and environment. Today, as the natural building sand became a limited and costly material, and fine aggregate is more economical and sustainable, this lead to the usage of fine aggregate in concrete technology. In this study, rubber granule aggregate (CRA) obtained from waste tyres with 0% (control), 5%, 10% and 15% ratios by weight was replaced with the amount of fine aggregate which remains at 1-2 mm sieve opening, and mechanical and morphological properties of the samples were investigated. For this purpose, unit weight, water absorption, compressive strength for 3,7 and 28 days, freezing-thawing (100 cycles) and ultrasonic pulse tests of concrete samples were performed. Also, SEM (Scanning Electron Microscope) images and EDS (Energy-Dispersive X-ray Spectroscopy) spectrum analyses of samples were examined. As a result of the study, it was determined that the sample containing CRA with 5% ratio gave more suitable results than the other samples.
