The Comparison of Using Andesite Waste Powder and Fly Ash in Concrete

Abstract

Andesite stone is widely used in civil engineering and architectural applications in Turkey. The production, cutting and polishing of the andesite stone by mining methods causes a large amount of waste. Some of them are big particular waste that is taken off pit and factories. And the others are powder waste derived during cutting in factories. These are wasted and not reclaimed. Andesite contains SiO₂ as the main component. Therefore, andesite may have pozzolanicity and thus may be used as mineral additive in concrete. In this study the usage of andesite waste powder as mineral additive in concrete is compared with F type fly ashes. In order to estimate the status of mineral additives in various replacement levels; the 28 and 90 days compressive strengths of concrete specimens were tested by preparing concrete specimens in different cement dosages. For C40/50 strength class, the optimum replacement rate of andesite waste powder was determined as 10% at curing ages of 28 and 90 days. The results of this study show that andesite waste powder can be used as mineral additive in concrete such as fly ash. The usage of andesite waste powder as a mineral additive at the optimal replacement ratios can achieve savings of, 20 kg cement for C40/50, 46 kg of cement for C55/67, and 52 kg of cement for C70/85.

Atık Andezit Tozu ve Uçucu Küllerin Betonda Kullanımının Karşılaştırılması

Abstract

Türkiye’de andezit taşı inşaat mühendisliği ve mimari uygulamalarda yaygın olarak kullanılmaktadır. Andezit taşının madencilik yöntemleriyle üretimi, kesilmesi ve cilalanması büyük miktarda atık oluşumuna neden olmaktadır. Bunların bir kısmı ocak ve fabrikadan çıkan iri parçalı atıklardır. Bir kısmı ise fabrikada kesim sırasında çıkan toz atıklardır. Bu atıklar değerlendirilmeden atılmaktadır. Andezit temel bileşen olarak SiO₂ içerir, bu yüzden andezit tozları puzolanik özellik gösterir ve betonda mineral katkı olarak kullanılabilir. Bu çalışmada andezit atık tozlarının betonda mineral katkı olarak kullanılması, F sınıfı uçucu küller ile karşılaştırılmıştır. Mineral katkıların farklı yer değiştirme seviyelerindeki durumunu belirlemek için, farklı çimento dozajlarında beton örnekleri hazırlanarak 28 ve 90 günde beton basınç dayanımları test edilmiştir. C40/50 dayanım sınıfı için, 28 ve 90 günlük kür yaşlarında atık andezit tozlarının en uygun yer değiştirme oranı %10 olarak belirlenmiştir. Çalışmadan elde edilen bulgulara göre atık andezit tozlarının uçucu küller gibi betonda mineral katkı olarak kullanılabileceğini göstermektedir. Mineral katkı olarak en ideal yer değiştirme oranlarında andezit kullanımı durumunda, C40/50 betonunda yaklaşık 20 kg, C55/67 betonunda 46 kg, C70/85 betonunda 52 kg çimento tasarrufu sağlanabilir.
