Nowadays, there are several research lines regarding how to improve rammed earth properties. Due to the lack of regulation for this material in Spain, the standard used as reference is related to fresh concrete. However, concrete and earth are completely different building materials. This paper presents the results obtained in earth samples that have been manufactured with the same percentage of initial water but they were hygroscopically stabilized at different relative humidities. Moreover, two types of rammed earth were studied using (1) lime water and (2) only water. The aim of this research is to evaluate how ambient conditions can influence compressive strength results of these two types of rammed earth.
