Formulation of Anti-Corrosive Coatings using Polyvinyl Acetate for Concrete Surfaces
Nivetha S, Selvaraj R, Lakshmi R
Abstract: The pores, capillaries, micro cracks, fissures, etc, created on the surface of concrete form defects. These surface defects allow for invasion of outer detrimental ions, which causes deterioration of concrete and corrosion of embedded steel in concrete. This corrosion of steel reinforcement becomes a severe concern to the life of Structures. One of the best ways to manage this durability issue is surface coatings to concrete. Coating usually covers all such defects and gives uniform durable surface finish. In this study, several coatings were developed by using polyvinyl acetate (PVA) as binder with functional pigments such as Silica fume, Nano silica, Kaolin, Alumina clay, TiO2, Al2O3, etc. , These coatings were subjected to Field exposure, Chemical exposure, Water absorption and Flame exposure and the best coatings were selected based on the screening tests and analysis. The selected coatings were finally subjected to various durability tests such as Sorptivity, Chloride ion diffusivity, Impressed voltage test and TAFEL extrapolation techniques.
