Atık cam ve yüksek fırın cürufu katkılı harçların özellikleri

Bu çalışmada, bağlayıcı olarak öğütülmüş atık şişe camlar ve endüstriyel yan ürünler içeren harçların özellikleri araştırılmıştır. Bu amaçla, iki farklı renkte camın tek başlarına ve cama ilaveten yüksek fırın cürufu’nun çimento ile çeşitli oranlarda yer değiştirmesi suretiyle oluşturulan harç numuneleri üretilmiştir. Numunelerin basınç dayanımı, NaCl, Na2SO4, MgSO4 ve yüksek sıcaklığa karşı dayanıklılıkları araştırılmıştır. Ayrıca ASR yönünden genleşme ölçümleri yapılmıştır. Basınç dayanımında % 10 renksiz cam-yüksek fırın cürufu yer değiştirmesinde en yüksek sonuç elde edilmiştir. Diğer dayanıklılık deneylerinde ise bütün yer değiştirme oranlarında referanstan yüksek sonuçlar elde edilmiştir.

Properties of mortars containing waste bottle glass and blast furnace slag

In this study, the properties of mortars that contain waste bottle glass and blast furnace slag as binding materials were investigated. For this purpose, specimens that were mixed with glass of two different colors alone and also together with glass mortar specimens where some amount of mortars were substituted with blast furnace slag were produced. The compressive strength test of specimens exposed to NaCl, Na2SO4, MgSO4 are investigated. Also, expansion calculations that were related to ASR were made. For compressive strength, on clear glass-blast furnace slag with substitution ratio of 10 %, the highest results were obtained. In all ratio substitutions higher result were obtained from the reference in the other resistance tests.
