Evaluates porcelain polishing residue's pozzolanic activity in self-compacting concrete, suggesting its potential for sustainable construction.

This research aims to assess the viability of using porcelain polishing residue as a supplementary cementitious material in self-compacting concrete.
Investigated pozzolanic activity of porcelain polishing residue using strength indices and modified Chapelle method.
Produced self-compacting concrete mixtures with varying PPR cement replacement levels.
Evaluated fresh, physical, and mechanical properties including compressive strength and matrix compactness.
PPR showed significant calcium hydroxide consumption, suggesting latent pozzolanic potential.
Fresh-state properties of mixtures were maintained with PPR inclusion.
An optimal replacement level of 20% enhanced long-term mechanical performance and reduced void content.
