摘要:
制作了体积掺量分别为(0.0%、0.2%、0.4%、0.8%和1.2%)的碳纤维水泥基材料,试件为100 mm×100 mm×100 mm的立方体.并比较其电导性能,试验研究了不同碳纤维掺量的混凝土在单调和循环荷载作用下其压应力和电阻率的关系.结果表明:随碳纤维掺量增大,阻抗曲线逐渐向左移动,在三维空间随机分布的纤维逐渐聚集并彼此连接,使复合材料的电导性能大幅增加.当碳纤维体积掺量同为1.0%时,不同龄期材料的交流阻抗谱相差很大,随着水化龄期的增长,C-S-H凝胶大量形成,水泥基材料中的溶液电阻逐渐增大,
Abstract:
Carbon fiber cementitious materials with volume content (0.0%, 0.2%, 0.4%, 0.8% and 1.2%) were fabricated, and the test pieces were 100 mm× 100 mm × 100 mm cubes. The conductivity performance was compared, and the relationship between compressive stress and resistivity of concrete with different carbon fiber content under monotonic and cyclic loads was experimentally studied. The results show that with the increase of carbon fiber content, the impedance curve gradually shifts to the left, and the fibers randomly distributed in three-dimensional space gradually aggregate and connect with each other, which greatly increases the conductivity of the composite. When the volume content of carbon fiber is the same as 1.0%, the AC impedance spectrum of materials of different ages varies greatly, and with the increase of hydration age, a large number of C-S-H gels are formed, and the solution resistance in cement-based materials gradually increases.
