Abstract

Bu çalışma deprem yıkıntı atıkları ve uçucu kül kullanılarak üretilen atık betonların taze beton özelliklerini yüksek doğrulukla tahmin edebilmek için sayısal bir model geliştirmeyi amaçlamaktadır. Bu amaç doğrultusunda farklı çimento dozajı, farklı su/çimento oranı, farklı uçucu kül ikame oranı içeren 24 farklı atık beton serisi üretilmiştir. Üretilen beton serileri üzerinde taze beton özelliklerini belirlemek için slump testleri uygulanmıştır. Elde edilen slump değerleri ve karışım miktarları dikkate alınarak tepki yüzeyi metodu üzerinde istatistik analizler yapılmış, sayısal bir model geliştirilmiştir. Geliştirilen modele ait belirlilik katsayısı 0.97 olup, tahmin sonuçları oldukça iyi düzeydedir. Aynı zamanda ek çimento esaslı malzeme olarak uçucu kül ile çimentonun yer değiştirilerek kullanılması, iri agrega olarak deprem yıkıntı atıklarının kullanılmasının sürdürülebilir kalkınma ve döngüsel ekonomi açısından büyük avantajlar sağladığı düşünülmektedir.

Development of Numerical Model to Predict Fresh Concrete Properties of Waste Concrete Produced Using Earthquake Demolition Wastes and Fly Ash

Abstract

This study aims to develop a numerical model to predict the fresh concrete properties of waste concrete produced using earthquake demolition wastes and fly ash with high accuracy. For this purpose, a series of 24 waste concretes with different cement dosages, water-to-cement ratios, and fly ash replacement ratios were produced. Slump tests were performed on the produced concrete series to determine the fresh concrete properties. Considering the obtained slump values and mix quantities, statistical analyses were performed on the response surface method, and a numerical model was developed. The coefficient of determination of the developed model is 0.97, and the prediction results are quite good. At the same time, it is thought that the use of fly ash as a supplementary cementitious material by replacing cement with fly ash and the use of earthquake demolition wastes as coarse aggregate provides great advantages in terms of sustainable development and circular economy.
