Özet:

 This study investigated the thermal properties of autoclaved aerated concreteAAC wall sections constructed with distinct mortars. Within the scope of the study, four distinct wall sections of 25x25x5cm dimensions were created using AAC special adhesive mortar, cement mortar, lime mortar and cement-lime mortar. The thermal conductivityλEXP that was determined by the heat flow meterHFM method and bulk densityρEXP of each wall section was determined in the laboratory. Specific heat valuescEXP of mortars and aerated concrete material were determined experimentally in the study. The thermal diffusivity valueαEXP, thermal effusivity valueeEXP and volumetric heat capacityVHCEXP of each wall sample were calculated using the experimental data obtained in the laboratory. In addition, αTEO, eTEO and VHCTEO of each wall sample were calculated theoretically using the thermal conductivity, bulk density and specific heat value given in the literature and standards for the same wall sections. In the study, experimental data was compared to the theoretical data. As a result, the thermal properties of walls constructed with distinct mortars and thermal differences formed in the walls due to the effect of these mortars could be determined with experimental data. However, it was observed that theoretical data were insufficient to detect these thermal differences.

 Bu çalışmada, farklı harçlar ile inşa edilmiş gaz beton duvar kesitlerinin ısıl özellikleri incelenmiştir. Çalışma kapsamında gaz beton özel yapıştırma harcı, çimento harcı, kireç harcı ve çimento-kireç harcı kullanılarak 25x25x5cm boyutunda dört farklı duvar kesiti oluşturulmuştur. Her bir duvar kesitinin, ısıl iletkenlik hesap değeri λEXP ısı akış ölçer HFM yöntemiyle ve birim hacim ağırlığı ρEXP standartlarda tarfilenen şekliyle laboratuvarda elde edilmiştir. Çalışma kapsamında kullanılan harçların ve gaz beton malzemenin özgül ısı değeri cEXP, deneysel olarak belirlenmiştir. Laboratuvarda elde edilen bu deneysel veriler kullanılarak her duvar örneğinin deneyselEXP termal efusiviteısıl dağınırlık αEXP, termal efusiviteısıl dağınırlık eEXP değeri ve hacimsel ısı kapasitesi VHCEXP hesaplanmıştır. Aynı duvar kesitleri için literatürde veveya standartlarda verilen teorik ısıl iletkenlik hesap değeri, birim hacim ağırlığı ve özgül ısı değeri kullanılarak her bir duvar örneğinin termal difüziviteısıl yayınırlık αTEO, termal efusiviteısıl dağınırlık eTEO değeri ve hacimsel ısı kapasitesi VHCTEO teorik olarak belirlenmiştir. Çalışmada deneysel veriler ile teorik veriler karşılaştırılmıştır. Sonuç olarak; farklı harçlarla inşa edilmiş duvarların ısıl özellikleri ve bu harçların etkisiyle duvarlarda oluşan ısıl farklılıklar deneysel veriler ile tespit edilebilmiştir. Teorik verilerin ise bu ısıl farklılıkları tespit etmede yetersiz kaldığı görülmüştür.
