Study on Fire Resistant and Noise Reduction Materials Used in the Tunnel

The paper explained the background of fire resistant and noise reduction materials lbr the tunnel, its research status and development trends. Background information described the tunnel fire, the tunnel fire resistant coating technology standards. Today there are many ways to protect the tunnel in the fire .Fire resistant coating is the best choice. The paper described the general components of the tunnel fire resistant coating and concrete raw materials. Especially describes the formula and characteristics of the existing coatings used in tunnel, which is belong to the inorganic coating, intumescent fire resistant coating and the complex, coating. Also it described the noise reduction applied in fire resistant coating. Finally, it discussed the forecast of the fire resistant and noise reduction coating used in the tunnel.
