Özet:

 Global warming is an important issue that closely affects all sectors, including the construction sector. For this reason, many initiatives are being carried out to develop materials that can be produced with low energy consumption. One of these can be considered as the use of waste paper in the production of building materials. In addition, the use of hollow lightweight masonry concrete blocks in terms of thermal insulation in buildings has also become quite widespread in recent years. This article aims to examine sustainable building elements with hybrid aggregates used in the construction of infill walls made of recycled waste paper and active origin expanded perlite and pumice. In the study, the mechanical properties, density and thermal insulation performance of the masonry blocks obtained using waste paper, pumice and perlite were evaluated in order to create environmentally friendly and sustainable alternatives in the production of lightweight building materials. It is aimed to develop building elements that are more cost-effective, environmentally friendly and energy efficient compared to traditional building materials with recycled materials such as waste paper. According to the results obtained, although the compressive strength of the material decreases with the increase in the use of waste paper, it has been observed that it can meet the required compressive strength criteria according to RILEM. Compressive strength values of cube samples after 28 days of curing were determined in the range of 2.76 MPa - 3.38 MPa. The use of 20 waste paper and 15 expanded perlite provided a 16.4, 15.2, 14.4 and 13.8 reduction in the unit weight of the masonry block in 110, 150, 180 and 200 doses of binder, respectively. In addition, it was observed that thermal conductivity coefficient values of 0.143 to 0.167 WmK could be achieved in lightweight blocks with the use of 35 waste paper. This study shows that hybrid aggregate structural elements can be used as a potential alternative for lightweight infill walls in the construction sector.

 Küresel ısınma, inşaat sektörü dahil olmak üzere tüm sektörleri yakından etkileyen önemli bir konudur. Bu nedenle, düşük enerji tüketimiyle üretilebilen malzemeler geliştirmek için birçok girişim gerçekleştirilmektedir. Bunlardan bir tanesi atık kağıtların yapı malzemeleri üretiminde kullanımı olarak değerlendirilebilir. Ayrıca, binalarda ısı yalıtımı açısından boşluklu hafif kagir beton blokların kullanımı da son yıllarda oldukça yaygınlaşmıştır. Bu makalede, geri dönüştürülmüş atık kâğıt ve aktif orijinli genleşmiş perlit ve pomzanın dolgu duvar yapımında kullanılan hibrit agregalı sürdürülebilir yapı elemanlarının incelenmesi amaçlanmaktadır. Çalışmada, hafif yapı malzemesi üretiminde çevre dostu ve sürdürülebilir alternatifler oluşturmak için atık kâğıt, pomza ve perlit kullanılarak elde edilen kagir blokların mekanik özellikleri, yoğunluk ve ısı yalıtımı açısından performansı değerlendirilmiştir. Atık kâğıt gibi geri dönüştürülmüş malzemelerle geleneksel yapı malzemelerine kıyasla daha düşük maliyetli, çevreye duyarlı ve enerji verimliliği sağlayan yapı elemanlarının geliştirilmesi hedeflenmiştir. Elde edilen sonuçlara göre, atık kâğıt kullanımının artışı ile malzemenin basınç dayanımı düşse de RILEMe göre gerekli basınç dayanım kıstasını sağlayabildiği gözlemlenmiştir. Küp örneklerinin 28 gün kür sonrası basınç dayanım değerleri 2,76 MPa  3,38 MPa aralığında belirlenmiştir. 20 atık kâğıt ve 15 genleşmiş perlit kullanımının kagir bloğun birim ağırlıklarında 110, 150, 180 ve 200 doz bağlayıcı kullanımlarında sırasıyla 16,4, 15,2, 14,4 ve 13,8lik hafiflemesini sağlamıştır. Ayrıca, 35 atık kâğıt kullanımı ile hafif bloklarda 0,143 ile 0,167 WmK ısı iletkenlik katsayısı değerlerinin sağlanabildiği gözlemlenmiştir. Bu çalışma, hibrit agregalı yapı elemanlarının inşaat sektöründe hafif dolgu duvarlar için potansiyel bir alternatif olarak kullanılabileceğini göstermektedir.
