Abstract

Enerji ve doğal kaynak tüketiminin sınırlandırılması fikri, günümüzdeki sürdürülebilirlik politikalarının odak noktasını oluşturmaktadır. Yüksek enerji gereksinimleri ve doğal kaynak tüketimleri sebebiyle çimento harçları için alternatif arayışı her geçen gün artmaktadır. Bu amaçla; bu çalışmada alkali-aktive edilmiş cüruf harçlarında atık cam tozu ilavesinin harç numunelerinin mekanik, por yapısı, termal iletkenlik ve mikro yapı özelliklerine olan etkisi araştırılmıştır. Atık cam tozu, harç karışımlarında ağırlıkça %15, %30 ve %45 oranlarında doğal kum ile yer değiştirilmiş ve tüm harç karışımlarında bağlayıcı malzeme içeriğinde çimento yerine ağırlıkça %50 oranında da cüruf tercih edilmiştir. Çalışmadan elde edilen sonuçlar, %15 seviyesindeki kum – atık cam tozu yer değişimi için sınırlı düzeydeki mekanik dayanım düşüşü ile termal yalıtkanlık özelliklerinin %35 düzeyinde artabileceğini ortaya koymuştur. Atık cam tozu katkılı alkali-aktive edilmiş cüruf harçları, üstün termal yalıtkanlık özellikleri ve sürdürülebilirlik politikalarına uyumlu çevre dostu özellikleri ile gelecekte çimento harçları yerine kullanılabilecek potansiyeli işaret etmektedir.

Mechanical, Pore Structure, Thermal Insulation and Micro Structure Properties of Alkali-Activated Slag mortars Containing Waste Glass Powder

Abstract

The idea of limiting the consumption of energy and natural resources is the focal point of today's sustainability policies. Due to its high energy requirement and natural resource consumption, the studies in order to develop an alternative for conventional cement mortars are increasing day by day. For this purpose; in this study, the effect of the waste glass powder inclusion on the mechanical, pore structure, thermal conductivity and microstructure properties of the alkali-activated slag mortars was investigated. Waste glass powder was utilized as a partial replacement of sand at contents of 15%, 30% and 45% by weight and slag was used in the binder content at a level of 50% as a replacement of cement in mixtures. The results obtained from the study revealed that the thermal insulation properties could be increased by 35% with a limited level of mechanical strength reduction for the replacement of sand with waste glasss powder at the level of 15%. The alkali-activated slag mortars containing waste glass powder indicate a great potential to be used in the future instead of conventional cement mortars with their superior thermal insulation and eco-friendly properties in compliance with sustainability policies.
