Overview

This investigation reveals EPS's role in fire resilience and spalling mitigation in high-strength mortar, suggesting careful temperature management is crucial.

Key Points

  • EPS incorporation prevented explosive spalling at 400 °C, while plain high-strength mortar suffered severe damage.
  • Both high-strength mortar and EPS-modified mortar showed strength gains at 200 °C, demonstrating temperature-dependent performance changes.
  • Thermal analysis indicated that EPS-enhanced insulation effectively reduced core temperatures during transient thermal exposure.
  • Microstructural changes revealed that EPS-induced voids can transition from beneficial to critical defects with increasing temperatures.
