摘　　要：为了解新型墙体——EPS空腔构造模块在发生火灾时的耐火性能,通过EPS空腔构造模块内部浇筑混凝土外侧涂抹不同厚度的抹灰层进行火灾模拟。试验结果表明,采用国际标准升温曲线进行火灾试验后,试件能满足耐火极限2 h要求,抗火性能良好。此外从稳定性和对火焰的阻燃作用方面综合比较,建议该墙体的最佳抹灰厚度为20 mm,为实际施工提供理论依据。In order to know fire-resistance performance of a new type of wall in the event of fire,the fire simulation was made by using the EPS hollow building module poured with concrete internally and applied with different thickness of plaster layer externally.Experimental results show that,after conducting fire test by adopting temperature rise curve of international standard,the specimens can meet the requirements of fire-resistance limit of 2 h,and the fire-resistance performance is good.In addition,with a comprehensive comparison from stability and flame retardation,it is recommended that the best thickness of wall plaster should be 20 mm,and this provides a theoretical basis for the actual construction.
