Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

Structural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.
