Mechanical performance and microstructural degradation of raw coal gangue aggregate concrete under chloride freeze–thaw exposure
This study investigated the influence of water freeze–thaw (WFT) and salt freeze–thaw (SFT) cycles on the mechanical performance and microstructure of concrete incorporating raw coal gangue aggregates (RCGA). Concrete specimens were prepared by replacing coarse natural aggregates (CNA) with RCGA at replacement ratios...
