摘要
利用碳纤维增强水泥混凝土 (CFRC)的导电性 ,可将其用于机场跑道融雪化冰 ,需要考虑的问题之一是CFRC在环境温度反复变化情况下的耐久性问题。本文采用实验的方法 ,模拟环境温度的反复变化 ,初步考察了CFRC的抗折、抗压强度的变化 ,及其与碳纤维含量、温度循环变化周次之间的关系 。
For the reason of the electrical conductivity of CFRC,it can be as a snow thaw material for the pavement of the airport.A problem which should be considered is the durability of the CFRC under the repeated temperature changed environment.In this paper,it's studied with bend and compressive test by simulating the environment.The result and its effective factors are analysed in terms of the microstructure of the material.
