Abstract

Use of Basalt Aggregate in Concrete Marine Structures Very high strength marine concrete, that can be placed without the use of vibrators, made up of CEM-I cement, blast furnace slag, silica fume and containing carboxylic admixture and including basalt coarse aggregate instead of limestone was experimentally investigated. The experiments carried out with the basalt specimen showed that the basalt used did not have alkali reactivity and also had high qualities as the limestone. Considering that there are different types of basalt in nature which can be defective, it must be emphasized that the successful results obtained in this study cannot be generalized without adequate preliminary investigations and applied to all basalts

Beton Deniz Yapılarında Bazalt Agrega Kullanımı

Abstract

Çok yüksek dayanımlı, vibratörsüz yerleşebilen, CEM-I çimento ve yüksek fırın cürufu, silis dumanı ve karboksilik akışkanlaştırıcı içeren deniz yapısı betonunun iri agregası olarak kireçtaşı yerine bazalt kullanımı deneylerle incelendi. Örnek bazaltın alkali reaktivitesi olmadığı, istenen yüksek niteliklere kireçtaşı düzeyinde sahip bulunduğu kanıtlandı. Farklı türde ve kusurlu bazaltların bulunduğu dikkate alınarak, başarılı sonucun yeterli ön incelemeler yapılmaksızın tüm bazaltlar için genelleştirilemeyeceği ve uygulanamayacağı vurgulandı

Keywords

• Bazalt, kireçtaşı, iri agrega, yüksek dayanım, işlenebilme, petrografi, alkali-silika
