ABSTRACT In this paper, we define the hygrothermal properties of a rammed earth wall through experimental analysis, relating thermal parameters to moisture content. These tests were conducted in Campo de Criptana (Ciudad Real, Spain), and the wall examined in this study is a 70-cm-thick north-facing rammed earth wall that is part of an occupied traditional dwelling Ambient and surface temperature and humidity values were monitored, along with the temperature and humidity at several points inside the wall and the heat flux on both sides of the wall. We recorded the wall’s behaviour regarding ambient comfort conditions for one year and obtained transmittance and conductivity values. Results show that it is quite difficult to analyse the hygrothermal behaviour of a rammed earth wall throughout the year, since the properties of the wall vary enormously. We found that, to evaluate the thermal behaviour of the wall, it was not appropriate to consider the same conductivity value for whole sections of the wall, as this value varies according to moisture content (generally between 0.39 and 0.55 Wm−1 K−1): we propose seasonal values for conductivity. Finally, the hygrothermal stability that these structures provide to the spaces they enclose has been shown, especially during hot and dry periods.

地中海干燥气候下传统土墙的湿热评估

摘要在本文中，我们通过实验分析定义了夯土墙的湿热特性，将热参数与水分含量相关联。这些测试是在 Campo de Criptana（西班牙雷亚尔城）进行的，本研究中检查的墙是 70 厘米厚的朝北夯土墙，它是传统住宅的一部分 环境和表面温度和湿度值以及墙内几个点的温度和湿度以及墙两侧的热通量进行监测。我们记录了墙壁关于环境舒适条件一年的行为，并获得了透射率和电导率值。结果表明，很难分析夯土墙全年的湿热行为，因为墙的特性差异很大。我们发现，为了评估墙的热行为，考虑墙的整个部分的相同传导率值是不合适的，因为该值根据水分含量而变化（通常在 0.39 和 0.55 Wm-1 K-1 之间） )：我们建议电导率的季节性值。最后，这些结构为它们所包围的空间提供的湿热稳定性已被证明，特别是在炎热和干燥时期。
