ELEVATED TEMPERATURE EFFECTS ON CONCRETE PRODUCED WITH RECYCLING AGGREGATE OBTAINED FROM CONCRETE SPECIMENS

Abstract

With the use of recycled aggregates (GDA) in concrete, it is aimed to protect natural aggregate resources, to reduce the demand for landfills, and as a result, to contribute positively to the environment in terms of sustainability. Except for the control group, during the concrete production phase, GDAs obtained from concrete wastes, which were subjected to 28-day strength test in ready-mixed concrete laboratories, were used as aggregate. GDAs were substituted for concrete by replacing 25%, 50%, 75% and 100% crushed stone aggregate. Within the scope of the experimental study, cylindrical samples of 100 mm x 200 mm dimensions were produced. The unit weights of the produced samples were determined. In addition, the compressive strength and capillary permeability results were determined after the samples were exposed to room temperature and temperatures of 100°C, 250°C, 500°C and 750°C. As a result, the use of GDAs produced from concrete wastes did not cause a significant decrease in the concrete compressive strength determined at room temperature. It was determined that the compressive strength results of the samples produced with GDA after high temperature (250°C, 500°C and 750°C) were higher than the kontrol sample.

Öz

Geri dönüştürülmüş agregaların (GDA) betonda kullanılması ile doğal agrega kaynaklarının korunması, düzenli depolama talebinin azalması ve sonuç olarak sürdürülebilirlik açısından çevreye olumlu anlamda katkı sağlaması amaçlanır. Bu amaçla, GDA kullanılarak üretilen betonların yüksek sıcaklık etkilerinden sonra özelliklerinin belirlenmesi için yapılan bu çalışmada; kontrol grubu haricinde, agrega olarak hazır beton laboratuvarlarında 28 günlük dayanım testine tabi tutularak kırılmış beton atıklarından elde edilen GDA’lar kullanılmıştır. GDA’lar betona %25, %50, %75 ve %100 oranında kırmataş agregası ile yer değiştirerek ikame edilmiştir. Deneysel çalışma kapsamında, 100 mm x 200 mm boyutlarında silindir numuneler üretilmiştir. Üretilen numunelerin birim ağırlıkları belirlenmiştir. Ayrıca numunelerin oda sıcaklığında ve 100°C, 250°C, 500°C ve 750°C sıcaklıklara maruz bırakıldıktan sonraki basınç dayanımı ve kılcal geçirimlilik sonuçları tespit edilmiştir. Sonuç olarak, beton atıklarından üretilen GDA’ların kullanımı oda sıcaklığında tespit edilen beton basınç dayanımında kayda değer bir düşüşe neden olmamıştır. GDA ile üretilen numunelerin yüksek sıcaklık sonrası (250°C, 500°C ve 750°C) basınç dayanım sonuçları, kontrol numunesine kıyasla daha yüksek olduğu belirlenmiştir.
