abstract = {Gypsum has historically been used as an additive in rammed earth construction
to enhance its mechanical properties. However, its application has declined
in modern practice, and scientific literature on gypsum-stabilized rammed
earth remains limited. This study investigates the effectiveness of gypsum as a
stabilizer to improve the compressive behavior of rammed earth, presenting it
as a sustainable alternative to Portland cement, which, despite its widespread
use, entails higher environmental and economic costs. To assess the influence
of gypsum, uniaxial compression tests were performed on rammed earth
specimens with varying gypsum contents (0%–15%). The results demonstrate
significant increases in compressive strength (up to 130%) and elastic modulus
(up to 262%) with gypsum inclusion, with the highest values recorded for the
15% gypsum-stabilized mixture (3.2 MPa and 267 MPa, respectively). Statistical
analysis, including analysis of variance (ANOVA), confirmed the significance
of these enhancements, with only the difference in elastic modulus between
the 10% and 15% mixtures showing no statistical significance. These findings
highlight gypsum as a viable eco-friendly solution for improving the mechanical
performance of rammed earth construction.},
