PURPOSE:To form a hardened cement body having good conductivity in which carbon fiber is uniformly dispersed by blending both carbon fiber and sulfate or thiosulfate with hydraulic composition. CONSTITUTION:This conductive cement is formed from carbon fiber, sulfate or thiosulfate and hydraulic composition. As sulfate or thiosulfate, sodium sulfate, potassium sulfate, magnesium sulfate, calcium sulfate, aluminum sulfate, sodium thiosulfate, potassium thiosulfate, calcium thiosulfate and anhydrous salt obtained by heating alum, etc., are used. Carbon fiber having 3-100mm fiber length and <=50mum fiber diameter is preferably used. As the hydraulic composition, portland cement, mixed cement, alumina cement and gypsum dihydrate, etc., are used. As the blending rate of the above-mentioned each component, carbon fiber is preferably regulated to <=6wt.% for the hydraulic composition and sulfate or thiosulfate is regulated to <=30wt.% therefor. |
