Nanotechnology in Repair and Protection of Structures State-of-the-Art


Sherief Abulmagd and Zeinab A. Etman

There can be many causes of deterioration in concrete structures. Concrete repaired is a specialist activity requiring fully trained and competent consultants and companies at all stages of the process. Often simple “patch and paint” strategies have been employed as short term cosmetic repairs which have failed to address the root cause of the problem and have, as a result, often failed to meet structure owners expectations. Nanotechnology provides insight into the use of nanomaterials in the following areas: Protection against ingress– moisture control– concrete restoratio – structural strengthening– physical resistance to chemicals– preserving or restoring passivity- increasing resistivity– cathodic control– cathodic protection control of anodic areas. This paper is state of the art for using nanotechnology in repair and protection of concrete structures. It is hoped that this paper will help researchers to be aware of the most recent progress in this important field.
