摘　　要：　目前碳纤维水泥砂浆的研究很多,而对于碳纤维混凝土的研究较为少见。作为结构材料必须加入粗骨料。粗骨料的引入使碳纤维混凝土力学和压敏性能较碳纤维水泥砂浆有较大的不同。本文介绍了碳纤维混凝土的试验室配制工艺及其电阻测量方法,并在此基础上研究了碳纤维混凝土的力学、压敏特性。通过综合比较相同条件下不同纤维掺量的混凝土其力学和压敏性能,确定了较为合理的碳纤维掺量。The mechanical properties and the sensitivity of carbon fiber reinforced concrete are different from those of the carbon fiber mortar because of the coarse aggregate.The mix proportion and the measurement method of the carbon-fiber reinforced concrete are introduced in this paper.The mechanical and pressure-sensitivity properties of the concrete are also involved.Reasonable fiber content is confirmed by comparing the comprehensive property of concrete with different fiber content in the same conditions.
