Study on Heat Conductivity Coefficient Value of Thick-Typed Fireproofing Coating for Tunnel at Elevated Temperature

Abstract:

In view of the issue that Heat Conductivity Coefficient (HCC) value of Thick-typed Fireproofing Coating (TFC) for tunnel at elevated temperature is not unknown, which makes researchers unable to make right fireproofing design and analysis for structure, starting from composition of TFC for tunnel, regarding it as complex of insulation aggregate and adhesive material, and using series model and parallel model, formulas of HCC at elevated temperature are established. The temperature field in three specimens is calculated by above HCC value, and is compared with testing results. Analysis result shows that HCC value from series model is the most reasonable. This paper provides an effective Solution for HCC value of TFC for tunnel at elevated temperature.
