Description

Technical field

[0001] The present invention belongs to the field of concrete technology, and more particularly to high strong conductive concrete with high slide of tailings and its preparation method thereof.Background technique

[0002] Concrete has been widely used in the field of civil engineering due to its excellent physical and mechanical properties, and is a building material for current dosage. The electrical resistivity of ordinary concrete is high, and the resistivity is generally 10.6~ 109In the range of Ωcm, a poor conductor belonging to the electricity. For alternating current, dry concrete is a good insulator with a resistivity of about 10.13Ωcm. However, with the increase in moisture in the concrete, the resistivity of concrete decreases. When the concrete moisture is completely saturated, the resistivity of concrete can be reduced to 102~ 103Ωcm. Therefore, ordinary concrete is a material between the insulator and the conductor. If a certain amount of conductive componen...
