Fire resistance tested: how plaster coatings on concrete columns stand up to extreme heat and what it means for design.
This book examines how different plaster mixes and reinforcement help protect steel-reinforced concrete columns during prolonged fires. It reports on tests using metal-lath forms, various plaster recipes, and even a specially insulated plaster mix, comparing how well each one preserves column integrity under four hours of fire exposure and heavy loading. The results shed light on practical trade‑offs between thickness, weight, and protective performance.
- See how ordinary plaster, gypsum-lime-sand plaster, and cement-cinder plaster perform under fire, including which layers stay in place and which crack or fall away.
- Learn how reinforcement like poultry netting influences insulation and bond between plaster coats.
- Understand how thin protective coatings can outperform thicker layers of traditional concrete protection.
- Get a sense of how these findings might guide design choices in buildings with concrete columns and fire safety requirements.
Ideal for readers of engineering fire safety, construction materials, and the behavior of protective coatings in extreme heat.
