Characteristics of Temperature Field of Rammed Earth Wall in Arid Environment

The rammed earth walls were greatly affected by the change of temperature fields in arid environments, particularly swell-shrink stress caused gradient variations was one main factors leading to surface weathering sites. While heat conduction, convection, and radiation resulting walls. In this study, thermocouple sensors embedded a rammed-earth test wall, continuously monitor field wall from near-surface area interior. results revealed that influenced seasonal together with significant changes daily differences. top thermal while interior foundation conduction. annual difference reached 62.99 °C, maximum on 24.3 which mainly appeared during spring autumn seasons. thickness temperature-sensitive less than 32 cm, within varied dramatically at depths 0–18 cm. 18–32 cm somewhat no obvious exceeding These trends indicate has an outstanding function preservation insulation. This study is expected be guidance reference for multi-field coupling environmental condition setting site bodies, strain field, mechanism strengthening technology as well related researches modern building designs.
