The degradation of concrete structures is a major issue faced by many countries around the world. Existing coating materials for surface protection and FRP for rehabilitation are less effective in prolonging the service life of concrete structures under severe environments. Available data on polymer- organoclay nanocomposites indicates the potential of this new kind of material to be employed as high performance coating and as matrix material of durable FRP to effectively enhance the durability of concrete structures under harsh environments. This book provides an in-depth...
