The problems for choosing crushed stones in making of carbon fiber conductive concrete for deicing or snow-melting are discussed.
讨论了将用于路面融雪化冰的碳纤维导电混凝土在制作过程中石子的选择问题,提出了在制作发热用导电混凝土铺层时,掺入石子应遵循的3个基本原则:石子的掺量不能太多;不能和标准的混凝土一样,采取合理的级配;掺入的碎石粒径不能太大。
The study provides a guide for the practical application of electrically conductive concrete in deicing or snow-melting.
详细研究了用于路面融雪化冰的碳纤维导电混凝土在各种不同条件下电阻的变化规律,包括中长期冻融循环、升降温循环、常温加热、低温加热等,得到了融雪化冰时合适的电源类别,为导电混凝土用于路面融雪化冰的工程实际提供了重要指导。
