Due to the increase in the number of energy structures day by day and the temperature increase in the soils around these structures, materials that can stabilize or even optimize their resistance against temperature are needed. In this study, compaction 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 is aimed to examine the seaweed additive from a thermal point of view. Thermal conductivity measurements showed that thermal conductivity increased as the algae 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.

Enerji yapýlarýnýn sayýsýnýn her geçen gün artmasý ve bu yapýlarýn çevresindeki topraklarýn sýcaklýðýnýn artmasý nedeniyle, sýcaklýða karþý direncini stabilize edebilecek, hatta optimize edebilecek malzemelere ihtiyaç duyulmaktadýr. Bu çalýþmada, ýsý yalýtýmýnda sýklýkla kullanýlan Zostera marina deniz tesisi kullanýlarak zeolit-bentonit ve deniz yosunu katkýlý karýþýmlarýn sýkýþtýrma ve ýsýl iletkenlik ölçüm testleri yapýlmýþtýr. Deniz yosunu katký maddesinin termal açýdan incelenmesi amaçlanmaktadýr. Isýl iletkenlik ölçümleri, karýþýmdaki yosun katkýsý arttýkça ýsýl iletkenliðin arttýðýný gösterdi. Ayrýca genel olarak sonuçlar, termal deðiþimlere karþý direnci yüksek olan deniz yosununun hem mevsimsel deðiþimler hem de enerji yapýlarýndan kaynaklanan termal deðiþimler varlýðýnda kullanýlabilecek alternatif bir katký malzemesi olduðunu göstermiþtir.
