Abstract

With the development of railways and highways, the construction of the tunnel are increasing, then the number of tunnel fires is also increasing, resulting in a large number of casualties and economic losses. The research breakthrough point of the tunnel fire prevention measures are mainly in two aspects of material and the structure[1].In all fire prevention measures, the fireproof coating has obvious advantages. It has good fire protection effect, high construction efficiency, no complicated construction technology and expensive equipment, will not produce pressure on the tunnel construction period. Aerogel mortar has many advantages of low thermal conductivity, good adhesive and hydrophobic properties. It is a better choice for fireproof coating materials. At present, the research on aerogel mortar is not yet advanced, and there is no relevant report about applying it for tunnel fire prevention. This paper studied the effect of the burning time, cooling mode and aerogel mortar coating on the strength of high performance concrete, and further summarized the law of the strength change of high performance concrete under the tunnel fire.
