“…This clay shows expected typical composition that consists of mainly SiO 2 and Al 2 O 3 which corresponds to about 71% (7) İ. Özkan because of the presence of clay minerals and quartz. Also, as typical Aegean region clay [11], these oxides are accompanied by a significant amount of iron oxide which is responsible for the reddish color after firing [12]. The high ignition loss (LOI) is due to the presence of volatiles, comprising in clay minerals and calcite.…”

The aim of this study is to characterize and determine the ceramic properties of the Turgutlu clay fired at various temperatures. For this purpose, the clay sample was first characterized by chemical analysis, X-ray diffraction, and plasticity measurements. The mineralogical composition of the Turgutlu clay was dominated by quartz, illite, mica, hematite, calcite, kaolinite, microcline, and smectite. The data obtained from plasticity tests indicated that the Turgutlu clay was very high plastic clay. To evaluate firing behaviors, pressed clay samples were fired separately at temperatures between 850 and 1100• C. Fired specimens were evaluated by water absorption, linear shrinkage, bulk density, flexural strength, X-ray diffraction, and scanning electron microscopy. Significant changes were observed such as an increase in the linear shrinkage and flexural strength together with a decrease in the water absorption above 1050• C. Based on the technological characteristics, the Turgutlu clay could be used in the manufacture of structural ceramics.

Rice husk ash is a residue that is generated when rice husk is burned. The high silica content makes this ash a waste with high economic potential. The waste clay used in this work is obtained from the processes employed at Eti Maden Bigadiç Boron Works. This study aims to recycle the waste clay and rice husk ash in the production of low-density ceramics. Rice husk ash and waste clay were characterized by chemical and Xray diffraction analyses. The batches containing different ratios of rice husk ash and waste clay were prepared and shaped by cold pressing. The pressed samples were fired at 950, 1000, 1050, and 1100˚C. The physical properties such as water absorption, apparent porosity, linear shrinkage, and bulk density were determined. Microstructural observations were performed by using scanning electron microscopy. Based on the technological characteristics; it was observed that low-density ceramics can be produced by using waste clay and rice husk ash. This study also supports the environmentally friendly recycling of waste clay and rice husk ash, which may have a storage problem.

“…The utilization of the different type of wastes in brick tile, and ceramic wastes in the different industries has been investigated as: waste-brick [13], granite wastes [14], coal fly ash [15], borax waste and dewatering sieve borax waste [15,16], ceramic roof tile [17], waste clay from gold mine [18], gneiss rock waste [19], ornamental rock-cutting waste [20], muscovite granite waste [21]. Reusing of tile waste and coal fly ash mixture has gained many features to the roof tile industry as low cost, environmentally friendly and energy efficiency raw material.…”

Abstract:The study presented in this manuscript focuses on the manufacturing of roof tiles bearing a mixture of tile waste and coal fly ash. A roof tile sample at a different composition was prepared to attain consistence in quality. The conversion factors were described to be able to convert the laboratory results for firing strength and water absorption into the industrial operating conditions. It was determined that the replacement mixture of the tile waste as well as the Tunçbilek fly ash together with the Muttalip clay as the raw material allowed the manufacturing of good quality roof tiles. Seyitömer fly ash was not suitable for use as secondary raw material due to the presence of tile waste with higher SO3 and CaO contents and lower MgO content. In addition to this, maximum 5 % Tunçbilek fly ash samples in the composition of roof tiles provided favorable physical and mechanical characteristics of the commercial product. Kiremit Atığı ve Kömür Uçucu Külü Karışımından Çatı Kiremiti Üretimi ve KarakterizasyonuAnahtar Kelimeler Çatı kiremiti, Atık, Kömür, Uçucu kül, Geri dönüşüm Özet: Sunulan bu çalışmada kiremit atıkları ve kömür uçucu kül karışımından kiremit imalatı üzerinde durulmaktadır. Kiremit örnek kalitesinin devamlılığını sağlamak için farklı kompozisyonlar hazırlanmıştır. Laboratuvar sonuçlarının endüstriyel çalışma koşullarına dönüştürmek için mukavemet ve su emme dönüşüm faktörü tanımlanmıştır. Kiremit atığının yanı sıra hammadde olarak Muttalip kil ile birlikte Tunçbilek uçucu külünün kullanılması ile kaliteli kiremit üretiminin gerçekleştiği bulunmuştur. Seyitömer uçucu külünün, yüksek SO3 ve CaO; ve düşük MgO içerği nedeniyle kiremit atıklarını ile beraber ikincil hammadde olarak kullanılmasının uygun olmadığı belirlenmiştir. Bununla beraber, çatı kiremiti bileşiminde maksimum %5 Tunçbilek uçucu külünün bulunması, ticari ürünün fiziksel ve mekanik özelliklerine olumlu katı sağlamıştır.
