Fracture behavior of rammed earth in historic buildings
Highlights The influence of soil:lime dosage on the density and ultrasonic pulse velocity of rammed earth test tubes was analyzed. The fracture energy and tensile strength values are related to the soil:lime dosage of the specimens. Rammed earth could be considered as a quasi-brittle material that follows Hillerborg's discrete crack model.
Abstract 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.
