Investigation of thermal properties of Zostera marina added zeolitebentonite mixtures

Abstract

The importance and number of energy structures are increasing, and due to the increasing temperature of the soil around these structures, materials that can stabilize or even optimize their resistance to temperature are needed. In this study, Standard Proctor test and thermal conductivity measurement tests of zeolite-bentonite and seaweed added mixtures were carried out by using Zostera marina sea plant, which is frequently used for thermal insulation. It was aimed to examine the seaweed additive from a thermal point of view. Thermal conductivity measurements showed that thermal conductivity increased as the seaweed contribution in the mixture increased. Also, generally the results indicated that seaweed, which has high resistance to thermal changes, is an alternative additive material that can be used in the presence of both seasonal changes and thermal changes caused by energy structures.

Zostera marina katkılı zeolit-bentonit karışımlarının termal özelliklerinin araştırılması

Öz

Enerji yapılarının önemi ve sayısı artış göstermektedir ve bu yapıların çevresindeki zeminlerin sıcaklığının artması nedeniyle, sıcaklığa karşı direncini stabilize edebilecek, hatta optimize edebilecek malzemelere ihtiyaç duyulmaktadır. Bu çalışmada, ısı yalıtımında sıklıkla kullanılan Zostera marina deniz bitkisi kullanılarak zeolit-bentonit ve deniz yosunu katkılı karışımların Standard Proctor deneyi ve termal iletkenlik ölçüm testleri yapılmıştır. Deniz yosunu katkı maddesinin termal açıdan incelenmesi amaçlanmaktadır. Isıl iletkenlik ölçümleri, karışımdaki yosun katkısı arttıkça ısıl iletkenliğin arttığını göstermiştir. Ayrıca genel olarak sonuçlar, termal değişimlere karşı direnci yüksek olan deniz yosununun hem mevsimsel değişimler hem de enerji yapılarından kaynaklanan termal değişimler varlığında kullanılabilecek alternatif bir katkı malzemesi olduğunu göstermiştir.
