The Investigation of Use as Aggregate in Lightweight Concrete Production of Boron Wastes

Lightweight concrete manufacture has been aimed as a result of the use of boron waste which is aggregate of pumice, one of our natural resources, and a valuable industrial waste as a substitution material in different proportions (1%, 3%, 5%, 7%, and 9%). As a result of the study, it was aimed to obtain a water-resistant and lighter material which has higher properties than lightweight concrete in terms of physical and mechanical. The study was carried out as three stages. At the first stage, 90% of the pumice aggregate and 10% of the sand (Reference sample) were used and lightweight concrete was produced. At the second stage, boron waste at the rate of 1%, 3%, 5%, 7%, and 9% was used for pumice aggregate and the doped lightweight concrete sample was produced. At the last stage, tests were carried out for the determination of the physical and mechanical properties of lightweight concrete samples which were produced. For determination of mechanical properties, tensile splitting strength and compressive strength tests were performed. Additionally, specific gravity, water saturated unit volume weight, porosity, and capillary water absorption tests were made for the determination of physical diversities. It was found that the physical and mechanical properties of the material improved with the increase of boron waste in the consequence of this study. The best result was obtained with the boron waste substitution at the rate of 9%. Environmentally harmful boron wastes being used in the construction sector will contribute to sustainability by recycling the boron wastes

Aerojelin Tuğla Üretiminde Kullanımı: Bir İnceleme

Brick is one of the building materials that has survived from the past to the present. It has not been able to meet the needs over time and has been improved. These improvements can be made with organic waste, industrial waste or new materials derived from them. One of the popular materials used for improvement in recent years is aerogel. Aerogel, which is used in many areas, has also started to be used in the construction industry. In this study, it was aimed to investigate the effects of aerogel on bricks by examining the studies on brick improvement with aerogel. In the study, articles and theses about aerogel were examined. As a result of the study, it was seen that aerogel improved some properties of the brick while negatively affecting some of its properties. It was also concluded that aerogel can be used in the re-functionalization of heritage structures. It has been determined that sustainable bricks with excellent thermal properties can be produced by using aerogel.Tuğla, geçmişten günümüze varlığını sürdürmüş yapı malzemelerinden biridir. Zaman içerisinde ihtiyaçları karşılayamamış ve iyileştirilmiştir. Bu iyileştirmeler organik atıklar, endüstriyel atıklar ya da bunlardan türetilen yeni malzemelerle yapılabilmektedir. Son yıllarda iyileştirme için kullanılan popüler malzemelerden biri de aerojeldir. Birçok alanda kullanılan aerojel, inşaat sektöründe de kullanılmaya başlanmıştır. Bu çalışmada, aerojelle tuğla iyileştirilmesi yapılan çalışmalar irdelenerek aerojelin tuğla üzerindeki etkilerinin araştırılması amaçlanmıştır. Çalışmada aerojel hakkında yapılan makale ve tezler irdelenmiştir. Çalışma sonucunda, aerojelin tuğlanın bazı özelliklerini iyileştirirken bazı özelliklerini olumsuz yönde etkilediği görülmüştür. Ayrıca aerojelin miras yapılarının yeniden işlevselleştirilmesinde de kullanılabileceği sonucuna varılmıştır. Aerojel kullanımı ile sürdürülebilir ve mükemmel termal özelliklere sahip tuğlalar üretilebileceği tespit edilmiştir
