Effect of Boron Wastes on the Engineering Properties of Perlite Based Brick

Abstract

The industrial development brings about the formation of wastes. These wastes can be reused in other sectors as byproducts to mitigate the harmful effects they have on the environment. One of the areas where these wastes are evaluated is in brick manufacturing for the construction sector. This study focuses on the use of industrial boron waste to improve physical and mechanical properties of bricks locally produced using perlite. In this study brick samples were produced by using boron wastes at ratios of 5%, 10%, 15% and 20% while keeping perlite materials constant at 5%. The samples were heated at 900 ° C. Physical and mechanical tests were performed on brick samples obtained after heating in the oven. Specific gravity, water-saturated unit volume, porosity and freezing-dissolution tests were performed to determine physical properties. In order to determine the mechanical properties, compressive strength and bending tensile strength tests were conducted to the brick samples. As a result, it is observed that the usage of perlite and boron wastes as additives in the production of bricks has desirable effects on improving physical and mechanical properties of bricks.

Bor Atıklarının Perlit Esaslı Tuğlanın Mühendislik Özelliklerine Etkisi

Öz

Endüstrinin gelişmesi atıkların oluşumunu beraberinde getirmektedir. Bu atıkların uygun sektörlerde kullanılması atıkların çevreye vereceği zararı minimize etmektedir. Bu atıkların değerlendirildiği alanlardan biri de inşaat sektörünün tuğla koludur. Bu çalışmada yerel malzemelerimizden olan perlit ve kıymetli endüstri atığı olan bor atığının tuğla yapı malzemesi özelliklerinin iyileştirilmesi üzerinde durulmuştur. Çalışmada tuğla bünyesine %5 perlit malzemesi sabit tutularak, %5, %10, %15 ve %20 oranlarında bor atığı ikame ederek tuğla numuneleri üretilmiştir. Üretilen numuneler 900 ° C'de pişirilmiştir. Pişirilme sonucunda elde edilen tuğla numunelerine fiziksel ve mekanik deneyler uygulanmıştır. Fiziksel farklılıklarının tespiti için özgül ağırlık, suya doygun birim hacim ağırlık, porozite ve donma-çözünme deneyleri yapılmıştır. Mekanik özelliklerinin tespiti için ise tuğla numunelerine basınç dayanımı ve eğilmede çekme dayanımı deneyleri uygulanmıştır. Sonuç olarak; perlit ve bor atığı katkısının uygun oranlarda tuğla üretiminde kullanılabileceği, kullanılması durumunda tuğla özelliklerine herhangi bir sakıncası olmadığı ve olumlu yönde etki sağladığı görülmüştür.
