Abstract

In this study, the physical and mechanical properties, durability, and natural light transmission density of transparent concrete are emphasized, and information is given about the properties and proportions of the materials used in its production, the companies producing the concrete and application examples. As a result, optical fibers (glass optical fiber, plastic optical fiber, etc.) are the most preferred materials among the materials with light transmittance (optical fibers, rubber, glass, etc.); their different placements and placement directions in concrete, different fiber ratios and fiber diameters affect the mechanical and physical properties of transparent concrete. Most of the research conducted in the last decade has focused on the light transmittance of concrete, suggesting that it will contribute to the structures aesthetically and reduce energy consumption, but no improvement studies have been made on its mechanical properties; and there is not enough information about the production of concrete that combines the benefits of both geopolymer concrete and light-transmitting materials. With this literature review, that new environmentally friendly transparent concrete can be designed and produced by considering the concepts of "industrial waste", "recycling", "sustainability" and "energy efficiency/ saving", which are mentioned a lot in today's engineering applications.

SAYDAM BETONUN ÖZELLİKLERİ ÜZERİNE BİR ÇALIŞMA

Abstract

Bu çalışmada, saydam betonun fiziksel ve mekanik özelikleri, dayanıklılığı ve doğal ışığı geçirme yoğunluğu üzerinde durulup, üretiminde kullanılan malzemelerin özellikleri ve oranları, betonu üreten şirketler ve uygulama örnekleri hakkında bilgi verilmiştir. Sonuç olarak, ışık geçirme özelliğine sahip malzemeler (optik fiberler, kauçuk, cam vb.) arasında en çok tercih edilenin optik fiberler (cam optik fiber, plastik optik fiber vb.) olduğu, bunların beton içerisinde farklı yerleşimleri ve yerleşim doğrultularının, farklı lif oranlarının ve lif çaplarının, saydam betonun mekanik ve fiziksel özeliklerini etkilediği gözlenmiştir. Son on yılda yapılan araştırmaları incelediğimizde çoğunun betonun ışık geçirme özelliği üzerine olduğu, estetik açıdan yapılara katkı sağlayıcı ve enerji tüketimini azaltacağı yönünde öneriler getirildiği, fakat mekanik özellikleri üzerinde herhangi bir iyileştirme çalışmaları yapılmadığı hem geopolimer beton hem de saydam malzemelerin faydalarını birleştiren beton üretimi konusunda yeterince çalışma olmadığı görülmüştür. Bu literatür taraması ile günümüz mühendislik uygulamalarında adı çok geçen “endüstriyel atık”, “geri dönüşüm”, “sürdürülebilirlik” ve “enerji verimliliği/ekonomik” kavramları ele alınarak çevre dostu yeni bir saydam betonun tasarlanıp, üretilebileceği kanısına varılmıştır.
