Multi-stage synergistic erosion mechanism of cast-in-situ concrete exposed to landfill leachate with varying COD concentrations.
The redevelopment of closed landfills exposes cast-in-situ concrete, a key infrastructure material, to complex landfill leachate immediately upon placement. This results in the simultaneous occurrence of hydration and degradation, posing a severe challenge to its long-term durability. To elucidate the degradation mecha...
