Implication

Randomized trial demonstrates the mechanical properties of unstabilized rammed earth, suggesting improved material characterization methods.

Key Points

This research aims to establish a multiscale experimental framework to characterize the physical and mechanical properties of unstabilized rammed earth (URE).
Characterization of soil composition, particle size distribution, Atterberg limits, and shrinkage at the soil scale.
Proctor tests to determine moisture content and density at the fabric scale.
Uniaxial compression and diagonal compression tests to assess strength properties at the specimen scale.
Compressive strength is isotropic with respect to loading direction; stiffness shows anisotropy with a coefficient of 2.6.
Proctor-based manufacturing reduces variability in compressive strength from 11.8% to 1.8%.
Shear strength is approximately 10% of compressive strength, aligning with established ratios for URE.
