石屑和天然砂于混凝土的抗火性研究

Research on fire resistance of concrete with aggregate chips and the one with natural sand

对石屑和天然砂于混凝土的应用进行了简要论述,将石屑和天然砂的物质特性作了比较,并对石屑和天然砂于混凝土在火灾中的表现进行了比较分析,得出天然砂混凝土对火灾的抵抗能力稍弱于石屑混凝土的结论。

The paper indicates application of the concrete with aggregate chips and the one with natural sand,compares the material features of the aggregate chips and natural sand,undertakes the comparative analysis of the performances of the concrete with the aggregate chips and the one with natural sand in fire accidents,and concludes the resistance of the concrete with natural sand is weaker than the one of the concrete with the aggregate chips.
