Title: ELECTRICAL CONDUCTIVE CEMENT-BASED COMPOSITE COMPOSITION
Abstract:
The present invention relates to an electrical conductive cement-based composite composition capable of exhibiting stable electrical performance since carbon nanotubes and carbon fibers are mixed in cement at a proper weight ratio so as to lower sensitivity to a specific resistance change caused by a change in a water/cement ratio (w/c). The electrical conductive cement-based composite composition according to the present invention comprises, in order to have stable electrical characteristics of which a specific resistance is 100 Ω·㎝ or less even with the change in the water/cement ratio (w/c), the cement, 0.1-0.5 wt% of the carbon nanotubes on the basis of the cement weight, 0.1-0.4 wt% of the carbon fibers on the basis of the cement weight, and silica fume and a superplasticizer as other additives.
