Implication

Randomized trial evaluates piezoresistive response in sustainable concrete mixtures, suggesting innovative real-time monitoring solutions.

Key Points

This research aims to evaluate the mechanical performance and piezoresistive response of sustainable concrete mixtures for structural health monitoring.
Developed six concrete mixtures (three high-strength and three conventional) incorporating recycled carbon fibres and EAF slag aggregate.
Assessed mechanical performance and piezoresistive response under static and cyclic loading conditions.
Investigated electrical behavior in different environmental conditions (dry, ambient, saturated).
The HSC mixture with rCF and short metallic steel fibres achieved a fractional change in resistivity of up to 93% under fatigue loading.
The CC-B mixture showed improved electrical sensitivity and mechanical resilience compared to other conventional concrete formulations.
Identified a biexponential kinetic law for the fatigue response connecting static and cyclic mechanisms.
