Ferrocement is a composite material consisting of layered wire meshes and rich cement-sand mortar which imparts high degree of ductility and energy absorbing capacity. Although ferrocement has proven itself as an excellent material for low cost housing, its durability continues to be a matter of concern owing to the corrosion susceptibility of the small diameter metallic wire meshes. Protection of reinforcement in ferrocement is usually achieved through the galvanized wire mesh, increased effective cover and dense mortar. These methods give only partial protection to the reinforcement against corrosion. This article reviews the studies undertaken to control corrosion in the ferrocement composites and thereby improving the durability of the composites.
