通过对掺不同外加剂的碳纤维增强水泥（CFRC）试件的电阻测试，考察了两种外加剂MKC和CKH的作用效果．结果表明它们有促进纤维分散的功效，配合相应的制备工艺，试块的导电性得到改善，压力作用下电阻变化的敏感性增强．还研究了龄期和纤维含量对试块电阻率的影响．由此可见，通过掺外加剂和选择合理工艺，可研制出导电性和压力敏感性良好的试件．

The effects of various specially made admixtures on properties of CFRC were studied. Theresults reveal that by using MKC, together with proper manufacturing technologyt the electricalconductivity, dispersion of fibre in cement and compression sensibility of CFRC are much improved,compared to the corresponding plAlN CFRC values. In addition, CKH can improve the electricalconductance of CFRC evidently.
