Abstract: Based on the vibration mixing technology, carbon fiber was selected as the conductive phase to prepare the conductive concrete for tower foundation grounding. The vibration mixing process parameters, mix proportion and grounding performance of carbon fiber conductive concrete were studied. The results show that the best combination of process parameters for the preparation of carbon fiber conductive concrete are: dry mixing time of 10 s, wet mixing time of 70 s and carbon fiber mixing time of 60 s. The best mix proportion is: carbon fiber content of 0.3%, water cement ratio of 0.46, unit water ues of 200 kg, sand ratio of 36%. Under this process parameter and mix proportion, the 28 d compressive strength and bending strength of the conductive concrete are 46.3 MPa and 5.7 MPa respectively, and the 28 d resistivity of the conductive concrete is 2.09 Ω·m, which has excellent electrical conductivity and meets the requirements of the grounding performance of the transmission line tower foundation.
