摘要

为保证纤维混凝土的高电阻率，在低体积含量范围内，对碳钢、聚丙烯-钢或钢-混杂纤维的不同组合进行了钢筋混凝土的试验试验。获得了(压缩、劈裂拉伸和弯曲)强度测试条件和峰后行为的最佳配筋成分。通过阻抗测量评价了为促进光纤均匀分布而采取的各种措施的效果。在测试过程中，通过显微镜和扫描电镜检查纤维分布。

Properties of Carbon-Steel and Polypropylene-Steel Hybrid Fiber Concrete in Low-Volume Fraction Range

This paper deals with trial testing on concrete reinforced by different combinations of carbon-steel, polypropylene-steel or steel-hybrid fibers in the low volume content range to ensure high electrical resistivity of the fiber concrete. Optimum reinforcement composition is obtained for (compression, splitting tension, and flexural) strength testing conditions and for post-peak behavior. The effect of various measures adopted to promote uniform fiber distribution are assessed by impedance measurements. During the testing program, fiber distribution is checked by microscopy and SEM.
