Electrochemical injection of nanoparticles into existing reinforced concrete structures
Original language description
This paper deals with the chloride extraction from concrete and shows possibilities of injection of selected nanoparticles and a hydrophobic agent into existing reinforced concrete structures by means of electromigration technique. Accelerated chloride penetration tests are employed to simulate natural chloride exposure. The developed chloride profile is then removed by electroextraction. Similarly, specimens are injected with different concentrations of colloidal nanosilica particles and a siliconate.It is shown in the paper that chlorides can be effectively extracted from the concrete using small voltage lasting for several days. Solutions of nanosilica and siliconate can be transported into concrete via the electric field. Once injected nanosilicacan act as a microstructure densifier and further reduce chloride penetration due to the decreased diffusivity of the treated concrete. Siliconate acts on hydrohobization of the outer specimen layer.
