Abstract

Various materials are added to the cement or concrete mixture in order to increase the quality of concrete in the construction sector. However, these materials sometimes improve some of the properties of concrete and some of its properties can be adversely affected. Numerous tests are needed to determine the effects of these additional materials on the concrete. However, this situation causes waste of time and material. In this study, the effects of the parameters on the compressive strength and porosity of the mortar samples with steel scale which is one of the waste materials of the iron and steel industry were investigated. Grey Relational Analysis (GRA) method was used to the optimization of these parameters. The four-parameter L16 orthogonal array was used to determine the experimental series. For this purpose, Mortar samples with different levels of fine scale, coarse scale, water/cement ratio and cement dosage were prepared and their compressive strength and porosity values were obtained. The data were evaluated by using Grey Relational Analysis method. As a result of the analysis, the optimum level of the parameters and the relationship between the compressive strength and porosity were determined.

Özet

İnşaat sektöründe betonun kalitesinin artırılması amacıyla çimentoya veya beton karışımı içerisine farklı malzemeler katılır. Fakat bu malzemeler bazen betonun bazı özelliklerini iyileştirirken bazı özelliklerini de ters yönde etkileyebilmektedir. Bu ilave malzemelerin beton üzerine olan etkilerinin tam olarak belirlenmesi amacıyla çok sayıda deneye ihtiyaç duyulmaktadır. Bu durum zaman ve malzeme kaybına neden olmaktadır. Bu çalışmada, demir-çelik endüstrisinin atık malzemelerinden biri olan çelik tufalin agrega olarak ilave edilmesi ile elde edilen harç numunelerindeki parametrelerin basınç dayanımı ve porozite üzerine olan etkileri incelendi. Bu parametrelerin optimizasyonu için Gri İlişkisel Analiz (GİA) yöntemi kullanıldı. Deney serilerinin belirlenmesinde dört parametreli L16 ortagonal dizininden faydalanılmıştır. Bu amaçla, farklı seviyelerde ince tufal, iri tufal, su/çimento oranı ve çimento dozajına sahip harç numuneleri hazırlanarak basınç dayanımı ve porozite değerleri elde edildi. Bu veriler Gri İlişkisel Analiz yöntemiyle değerlendirildi. Yapılan analizler sonucunda, optimum seviyeler ve basınç dayanımı ile porozite arasındaki ilişki belirlendi.
