In modern buildings, it is of great importance that masonry walls are constructed with light and durable materials and at the same time have low thermal conductivity. Increasing lightness, durability and resistance to heat transfer in such elements contributes to reducing heating and cooling loads while reducing the building load. Especially in the production of raw perlite-based lightweight concretes, expansion can be achieved by adding Hydrogen Peroxide (H2O2). In this study, raw perlite-based lightweight structural elements using 1%, 2%, 3% and 4% H2O2 addition were experimentally examined. The results obtained showed that the addition of 3% H2O2 gave the best results, while the addition of 4% caused excessive swelling and structural disintegration in the perlite particles. Additionally, the relationship between bending strength, compressive strength and thermal conductivity performance was evaluated with the H2O2 ratio used.

Modern yapılarda yığma duvarların hafif ve dayanıklı malzemelerle inşa edilmesi, aynı zamanda düşük ısı iletkenliğe sahip olması büyük önem taşımaktadır. Bu tür elemanlarda hafiflik, dayanıklılık ve ısı geçişine karşı direncin artırılması bina yükünü azaltırken ısıtma ve soğutma yüklerini azaltmaya katkı sunmaktadır. Özellikle ham perlit temelli hafif betonların üretiminde, Hidrojen Peroksit (H2O2) ilavesiyle genleşme sağlanabilmektedir. Bu çalışmada ise %1, %2, %3 ve %4 oranlarda H2O2 ilavesinin kullanıldığı ham perlit esaslı hafifi yapı elemanlarının deneysel olarak incelemesi yapılmıştır. Elde edilen sonuçlar, %3 oranında H2O2 ilavesinin en iyi sonuçları verdiğini, %4 ilavesiyle perlit taneciklerinde aşırı şişme ve yapısal dağılma meydana geldiğini göstermiştir. Ayrıca, eğilme dayanımı, basınç dayanımı ve ısı iletkenlik performansı arasındaki ilişki, kullanılan H2O2 oranıyla değerlendirilmiştir. TGA ve DTA analizine göre numunenin kütle kaybına uğradığı sıcaklık dereceleri belirlenmiştir.
