摘　　要：本试验研究各种石材在各种火害的情况下,石材对混凝土的保护效果,石材施工方法使用湿式贴法,温度则考虑常温(25℃)以及火害温度500℃、700℃与900℃,火害延时皆为30 min。然后以25顿MTS材料试验机进行混凝土梁四点抗弯试验,研究结果显示,火害温度500℃、700℃与900℃后,无论任何石材贴覆之混凝土梁强度皆高于火害后的纯混凝土梁。The test study of various kinds of stone in the case of fire victims, stone protective effect of concrete, stone construction method using a wet paste method, the temperature is considered normal temperature （25 % ） and thermal damage temperature 500 ℃, 700 ℃ and 900℃ fire victims are all 30 min delayed. Then 25 Dayton MTS material testing machine concrete beam four-point bending test, the results showed that the fire damage temperature 500℃, after concrete beam intensity stone veneer cladding of the fire victims 700℃ and 900 ℃, regardless are higher than the pure concrete of any beam.
