| 摘要 |
The present invention concerns a process for orienting and accelerating the formation of concretions in marine environment, wherein a metallic cathode having a shape corresponding to the skeleton of the concretion to be formed and an anode made of a metal or a metal alloy which is more electronegative than the metal or the alloy of the cathode are used, by immersing the anode and the cathode in an amphoteric electrolyte containing magnesium, calcium and carbonate ions, such as sea water, and by electrically interconnecting the two electrodes, and an apparatus for practicing the same. The process is characterized in that the ratio of the surface of the anode to the surface of the cathode is between 1/30 and 2/1, with the anode mass sufficient to maintain this ratio within said limits during a period of time comprised between a few days and one year. Application to the formation of artificial reefs, the consolidation of marine soils, or stopping cracks in submerged constructions, etc.
