The relevance of concrete is growing in the modern world due to population growth and technological advancement. The necessity for specialty concrete arises from the various usage regions in the constructions. Foam concrete is one of the most useful varieties of special concrete because it offers insulation from heat and sound. The mechanical and physical properties of foam concrete are influenced by a variety of elements. The characteristics of foam concrete are substantially impacted by the mineral admixtures. The physical and mechanical impacts of fly ash (FA), fine sand, and expanded perlite (EP) admixtures on foam concrete were examined in this experimental investigation. On samples made from fly ash, sand, and expanded perlite, 15 various ratios of foam concrete mixtures were tested physically and mechanically (compressive strength, Marsh cone, ultrasonic pulse velocity, and thermal conductivity), as well as microstructurally (SEM). The foam concrete samples' compressive strength values were above 1.5 MPa, which is in compliance with TS 13655. According to the Marsh cone test, the flow duration of all the samples decreased as the weight of the fresh mortar increased. In all samples, the density increased along with the ultrasonic pulse velocity.

Uçucu Kül, İnce Kum ve Genleştirilmiş Perlitin Köpük Beton Özelliklerine Etkisinin Araştırılması

Öz

Günümüzde nüfus artışı ve teknolojinin gelişmesi betonun önemini artırmaktadır. Yapılarda farklı kullanım alanları özel beton ihtiyacını da beraberinde getirmektedir. Hafiflik, ısı ve ses yalıtımı sağlayan köpük beton, özel betonlar arasında en işlevsel beton türlerinden biridir. Köpük betonun fiziksel ve mekanik özelliklerini birçok faktör etkiler. Mineral katkılar köpük betonun özelliklerini önemli ölçüde etkiler. Bu deneysel çalışmada, uçucu kül (FA), ince kum ve genleştirilmiş perlit (EP) katkılarının köpük beton üzerindeki fiziksel ve mekanik etkileri araştırılmıştır. Uçucu kül, kum ve genleştirilmiş perlit kullanılarak elde edilen 15 farklı oranlı köpük beton karışımları üzerinde fiziksel ve mekanik testler (basınç dayanımı, Marsh konisi, ultrasonik darbe hızı ve termal iletkenlik) ve mikroyapı (SEM) incelemeleri yapılmıştır. Köpük beton numunelerinin basınç dayanım değerleri TS 13655 standardını karşılayan 1.5 MPa'nın üzerindedir. Marsh koni testi, tüm numunelerde taze harç ağırlığının artmasıyla numunelerin akış süresinin azalmasına neden olmuştur. Ultrasonik darbe hızı, tüm numunelerde artan yoğunlukla artmıştır. Uçucu kül ile üretilen köpük beton numunelerinin ince kum ile üretilen numunelere göre daha düşük iletkenliğe sahip olduğu sonucuna varılmıştır. Ayrıca uçucu kül puzolanik özellikler göstererek dayanım geliştirmede etkili olmuştur. Köpük betondaki uçucu kül, ince kum ve genleşmiş perlit katkıları, köpük betonun fiziksel ve mekanik özelliklerini iyileştirmiştir.
