Implication

This research investigates compressive strength and microstructure evolution in coal gangue cement, suggesting eco-friendly waste management solutions.

Key Points

The compressive strength of the Cemented Gangue Filling Body reached 4.18 MPa after 28 days.
Sodium silicate and lime activated latent substances, converting them into useful hydration products.
Microstructural analysis revealed significant reductions in porosity from 10.5% to 3.8% over time.
The findings support resource treatment of solid waste and enhance applications in mining materials.
