Abstract

Ignimbrites (Ahlat Stone) with macro and micro-sized pores possessing independent of each other are volcanic rocks. It is mainly used as a building material because of its excellent insulation and easy to form material. The present study is aimed at producing floor tile which incorporated Ahlat stone as an alternative raw material for the ceramic industry. The effects of the increasing amount of Ahlat stone (1, 3 and 5 wt%) in the recipes on slurry rheology, physical properties of ceramic tiles, and sintering were studied. Chemical components of raw materials and Ahlat stone were determined using X-ray fluorescence spectroscopy and accordingly the recipes were created. The surface morphology of tiles was scanned using scanning electron microscope. When 3% Ahlat stone was added to the recipe, the flexural strength was calculated as 540 kgf.cm−2. This value is 22% higher than the value which is specified in the TSE standards. Therefore, tiles with a longer lifetime and more durability were developed. In addition, the increased amount of Ahlat stone in the recipe reduced the sintering temperature, thus energy saving was achieved during firing. GRAPHICAL ABSTRACT

阿勒特石废料在瓷砖生产中的增值:物理-机械性能

火成岩(Ahlat Stone)是一种具有相互独立的宏观和微观孔隙的火山岩。它主要用作建筑材料，因为它具有优异的绝缘性和易于成型的材料。目前的研究旨在生产地砖，其中包括阿勒特石作为陶瓷工业的替代原料。研究了配方中阿勒特石添加量(1、3、5 wt%)对浆料流变学、瓷砖物理性能和烧结性能的影响。利用x射线荧光光谱法测定原料和阿赫拉特石的化学成分，并据此制定配方。用扫描电镜对瓦片表面形貌进行了扫描。当配方中加入3%的阿勒特石时，计算出的抗弯强度为540 kgf.cm−2。这个值比TSE标准中规定的值高22%。因此，开发了寿命更长、耐久性更高的瓷砖。此外，配方中阿勒特石用量的增加降低了烧结温度，从而达到了烧制过程中的节能效果。图形抽象
