Résumé
Rammed earth is the construction system of many heritage structures and buildings in
different regions of the planet, some of which are seismically active areas. For this reason,
these historic buildings can sustain structural damage or have already been subjected to
stresses that have led to high levels of cracking in the rammed earth walls. Therefore,
knowledge of the fracture behavior of this material is essential to assess the actual state
of structural safety and the remaining mechanical capacity. The number of studies on the
fracture behavior of rammed earth is limited, and even fewer studies have considered lime
as a stabilizer and used traditional materials. This study measured the density, ultrasonic
pulse velocity, fracture energy and tensile strength of prismatic specimens with two
different soil: lime dosages and found relationships between the different parameters
analyzed and the dosages used. Finally, it was verified that the fracture behavior of
rammed earth can be assumed to be similar to that of mass concrete from a qualitative
standpoint. For this reason, rammed earth could be considered as a quasi-brittle material
that follows Hillerborg's discrete crack model.
