Comparative study reveals superior high-temperature performance of lightweight ultra-high performance concrete, indicating potential benefits for construction materials.

Key Points

This research focuses on comparing the performance of ultra-high-performance concrete and its lightweight variant under high-temperature conditions.
Conducted tests on flexural strength and crack evolution at various temperatures including 20°C, 200°C, 400°C, and 600°C.
Applied acoustic emission technology to analyze bending damage mechanisms.
Utilized scanning electron microscopy to assess microstructural characteristics post exposure.
L-UHPC demonstrated a 17.1% reduction in flexural strength at 600°C, which is less compared to UHPC.
L-UHPC maintained a lower shear crack ratio at elevated temperatures, indicating better ductility.
Both materials exhibited significant cracking at the fiber-matrix interface, with L-UHPC showing less severe damage.
