Related Studies to Cathodic Protection of Reinforced Concrete Structures

摘要

A study of making an asphaltic concrete conductive was accomplished using coke breeze mixed with asphalt and aggregate. Mixes containing 45% coke breeze, 7-11% asphalt and the remainder a standard aggregate were found to be appropriate for conductive layers for cathodic protection. Testing in the laboratory and bridge decks of molybdneum-molybdneum oxide electrodes indicated these would be useful as embeddable reference electrodes in concrete. Reinforced concrete cylinders were exposed to cathodic protection level currents for five years. Pullout strengths and concentrations of sodium, potassium and chloride ions were determined throughout this time period.
