菱镁免蒸多孔材料的耐久性研究

Research of the durability of non-steaming magnesite porous materials

将菱镁多孔免蒸气养护材料在露天自然堆放二年，并对其各项性能指标进行了全面测试，经综合分析评价，提出了自然风霜雨雪及温度、湿度变化对该材料劣化的影响．

The non --steaming magnesite porous material was piled up in the open for two years,and the various abilities of the material were tested comprehensively. Acording to the comprehensive analysis and evaluation,that temperature,humidyty and various nature states affect the detevioration of the material is given.
