摘　　要：在自密实混凝土配合比的基础上,制备不同掺量纳米碳纤维混凝土,并采用自行设计的数据采集系统研究了各混凝土试件的压敏性能。结果表明：采用普通制作工艺和自密实混凝土技术,可使纳米碳纤维均匀分散在混凝土材料中,当掺入胶凝材料体积0.8%~1.0%的纳米碳纤维掺量时可制备出压敏性优良的智能混凝土材料。Concrete specimens were prepared by adding different dosages of carbon nanofiber in the mixture of self-compacting concrete. The peizoresistive effect of such concrete specimens were evaluated by using a self-setup data acquiring system. The results show that carbon nanofiber can be well dispersed in concrete with the traditional manufacture process when the mixing prorportion of self-compacting con- crete is adopted. And smart concrete material with excellent piezoresistive effect can be prepared by adding 0. 8 to 1.0 percent of carbon nanofiber by volume of total binder.
