ELECTRO-KINETIC TECHNIQUE FOR ENHANCING DURABILITY OF CONCRETE

Electro-kinetic treatment has been recognized as a promising technology for different purposes in civil engineering. Durability of structures is of global concern, many engineers and researchers are working to enhance durability of concrete elements. The main focus of the present study is to improve the durability of cement concrete by application of electro-kinetics. This method can be used practically used in pre-cast members like railway sleepers, girders and other precast and prefabricated structural elements. The durability of concrete can be improved by pore filling effect by ionic migration by adopting electro-kinetic concepts. It is suggested in this paper electro-kinetic principle with selected electrolyte, applied voltage with appropriate duration can be utilized for enhancing the durability of concrete. Chloride Ion Penetration tests, Compression test, Corrosion study and FESEM studies were also done as evaluation tests.
