Silis dumanı yüksek sıcaklık ürünü seramik bir malzemedir. Endüstriyel bir atık olan silis dumanına bu özelliği refrakter yapısı kazandırmaktadır. Endüstriyel atıklar tüm dünyada olduğu gibi ülkemizde de küçümsenmeyecek miktarlarda çevresel problemlere sebep olmaktadır. Bu atıkların değerlendirilmesi çevre problemlerinin çözümüne ve ekonomik girdilere katkı sağlamaktadır. Bu çalışmada, endüstriyel refrakter atık bir malzeme olan silis dumanı termal yalıtım malzemesi üretiminde kullanılmıştır. Üretilen yalıtım tuğlasında, silis dumanı, sönmüş kireç ve su kullanılmıştır. Tuğla macunu, silis dumanı atıkları, su ve kireç farklı ağırlık oranlarında karıştırılmak suretiyle kullanılmıştır. Üretilen ısı yalıtım malzemesinin özelliklerini değerlendirmek için, elde edilen tuğlanın fiziksel, mekanik ve mikro yapı özellikleri test edilmiştir. Bağlayıcılık oranına göre 1.2 oranında silis dumanı katılan tuğla düşük yoğunluk ve yüksek mekanik mukavemet bakımından iyi özellikler göstermiştir.

Experimental Investigation of Refractory Insulation Material Production

The silica fume which is the high temperature product is a ceramic material. A refractory structure gives that feature to the silica fume which is an industrial waste. Industrial wastes cause environmental problems in quantities that cannot be underestimated in our country as it is in the whole world. The utilization of these wastes contributes to the solution of environmental problems and to economic inputs. In this study, the silica fume which is an industrial refractory waste was used in thermal insulation material production. Silica fume, slaked lime and water were used in the insulation brick produced. The brick paste was prepared by mixing silica fume wastes, water and lime at different weight ratios. The physical, mechanical and microstructural properties of the produced brick were tested to evaluate the properties of the manufactured insulation material. According to the binder ratio, the brick which silica fume added in 1.2 ratio showed good properties in terms of low density and high mechanical strength.
