An Overview on Effects of Water Repellent Concrete Protective Coatings in the Durability of Concrete Structures

The emergence of concrete structures is increasing day by day. Out of these, some of them under go faster deterioration based on the environment in which it is placed. So it is very important to protect and maintain the structures to make it durable throughout its service life. Durability is the ability of structures to resist the environmental attacks without deterioration. Lack of durability is the major concern faced by most of the structures. Durability is achieved by preventing the attack of environmental factors like weathering, freeze and thaw reaction etc. One of the methods to prevent these attacks is by the application of water repellent protective coatings on the surface of concrete, which gets exposed to environmental attacks. This paper is a review about the various studies on the effect of different types of concrete protective coatings on the durability of concrete.
