PURPOSE: A conductive cement composition having excellent adhesibility with soil is provided, which keeps the conductibility and minimizes the contact resistance with the soil. And a conductive hardened body prepared therefrom is also provided. CONSTITUTION: The conductive cement composition comprises: (i) 100 part by weight of soil binding agent comprising 10-40 wt.% of clinker powder which is mainly composed of calcium sulpho-aluminate mineral, 1-30 wt.% of portland cement, 10-40 wt.% of quicklime or calcium hydroxide, 5-30 wt.% of anhydrite and 0.1-2.0 wt.% of fluosilicate; (ii) 0.1-2 part by weight of admixture; and (iii) 0.5-2 part by weight of carbon fiber. The conductive hardened body is prepared by mixing the conductive cement composition with filler and then hardening the mixture by hydration.
