High-Temperature Residual Strength and Microstructure in Air-Entrained High-Strength Concrete

Use of high-strength concrete (HSC) in built infrastructure allows efficient structural systems with higher strength and durability. However, HSC being sensitive to high temperatures results in reduced residual strength after fire exposure, which impairs post-fire structural serviceability. This low...
