Abstract

This paper reports an experimental investigation carried out to evaluate the mechanical properties of structural lightweight concrete produced with pumice and mineral admixtures. CEM I 42,5 N cement used in the study was partially replaced with silica fume (SD) 10% and fly ash (UK) 30% by weight, respectively. The tests of compressive strength, split tensile strength and ultrasonic pulse velocity were performed in the specimens prepared with mineral admixtures at ages of 3, 7, 14, 28 and 90 days. From the results it was seen that specimens prepared with silica fume showed better strength properties than other test specimens. While control concrete specimens showed similar strength properties to concrete specimens with silica fume admixture at early ages those of concrete specimens with fly ash admixture did not increase at early ages. Furthermore, UK concrete series gave very close results to control concrete at advanced ages (90 days).

Özet

Bu çalışmada, pomza ve mineral katkılı taşıyıcı hafif betonun mekanik özellikleri araştırılmıştır. Çalışmada CEM I 42,5 N sınıfı çimento kullanılmış olup mineral katkı olarak kullanılan silis dumanı (SD) %10 ve uçucu kül (UK) %30 oranlarında çimento ile ağırlıkça yer değiştirilmiştir. Kullanılan katkılarla birlikte hazırlanan 3, 7, 14, 28 ve 90 günlük numunelere basınç, yarmada çekme dayanımı ve ultrasonik test deneyleri uygulanmıştır. Elde edilen sonuçlara göre silis dumanı katkılı beton numunelerin her yaşta daha iyi dayanım özellikleri sergilediği görülmüştür. Kontrol betonu olarak hazırlanan numuneler ilk yaşlarda silis dumanı katkılı beton numunelerle benzer özellikler sergilerken uçucu kül katkılı beton serilerinde erken yaşlarda belirgin bir artış gözlenmemiştir. Bununla birlikte UK beton serisi ileri yaşlarda (90 gün) kontrol betonuna daha yakın sonuçlar vermiştir.
