Overview
Enabling low-carbon PSC sleepers without changing track standards
Conventional PSC sleepers use cement and natural aggregates with high CO₂ impact.
Natural aggregate depletion and rising material costs increase supply risk.
Rail projects need a low-carbon alternative compatible with current specifications.
This technology replaces 30% cement with GGBF slag and uses steel slag as aggregate.
It delivers slag-based PSC sleepers and expandable PST panels with verified performance.
