Fire Performance of Hybrid Fibre Reinforced Concrete with Steel and Sodium Carbonate-Treated Natural Fibres Under Standard Fire Exposure
This study investigates the fire behaviour of hybrid fibre reinforced concrete (HFRC) incorporating steel fibres combined with coir, polypropylene (PP), ramie, and sisal fibres under the ISO 834 standard fire curve. Concrete specimens were exposed to fire for 15, 30, and 60 min, and their residual compressive, split te...
