摘要
研究了C60普通砂和机制砂高性能混凝土在两种受火方式下的耐火性能。研究结果表明,机制砂混凝土与普通砂混凝土耐火性能相当;掺加纤维能够改善混凝土的耐火性能;混凝土中单掺合成纤维或钢纤维其耐火性能相差不多,钢纤维与合成纤维混杂应用效果最好。
The fire resistances of C60 high performance concrete in two kinds of fire conditions were studied. The concretes were respectively made by manufactured sand and normal aggregates. The results show that the fire resistance of manufactured sand concrete is equivalent to that of normal concrete. The fire resistance can be improved by adding fibers. The effect of using steel fibers and synthetic fibers together is the best but nearly the same as that of using them alone.
