Abstract
nEvaluating the mechanical performance and environmental benefits of geopolymer composites is
imperative for sustainable alternatives in construction. This study presents an innovative circular
PZT-based sensor that effectively captures transient vibrations within concrete structures,
demonstrating its validity in comparison to standard surface-mounted accelerometers. The research
also elucidates the influence of sensor orientation on capturing various vibrational modes of
concrete. Furthermore, the embedded PZT sensors provide valuable insights into the evolving
mechanical properties of hydrating concrete, offering a continuous measure of concrete stiffness as it
ages. In the context of geopolymer concrete, the study showcases its environmental benefits by
comparing it with conventional cement-based concrete in the form of interlocking paver blocks. The
results reveal that geopolymer concrete, particularly the variant incorporating 100% GGBS, exhibits
superior compressive strength, reaching 92.17 N/mm² compared to 54.2 N/mm² for conventional
concrete. Additionally, PZT sensors successfully identify cracks in geopolymer composite,
highlighting its potential for improved mechanical properties and reduced environmental impact in
the construction industry.
