This chapter presents the materials used for the seismic retrofit of structures covered by modem retrofit design codes and recommendations such as reinforced concrete, steel, and composite stmetures as well as masonry stmetures (EC8-3 2005 FEMA 547 2006 Fardis 2009 CNR-DT 200/2004). It discusses materials for both repair and strengthening of contemporary stmetures with special focus on reinforced concrete buildings and bridges (Priestley et al. 1996 Fardis 2009) as well as on advanced materials (high-performance cement-based materials, shape-memory alloys, fiber-reinforced polymers, textile-reinforced mortars, etc.). 

A rather broad definition proposed by the ACI 549.2R-04 for ferrocement is A type of thin wall reinforced concrete constructed of hydraulic cement mortar reinforced with closely spaced layers of continuous and relatively small wire diameter mesh. The mesh may be made of metallic or other suitable materials. In this definition all kinds of non-metallic meshes are included, as well as fabrics and mats made with non-metallic fibres that are treated as textile reinforcement. 

Textile reinforcement is applied for several types of cement mortar or concrete products ...

This section further deals with the mechanics of continuous reinforcement based on the use of modern textile yarns, made of an assembly of yarns consisting of numerous filaments with a diameter of 10-50 pm. In these systems several hundreds or thousands of filaments are assembled into a strand, and several strands are assembled into a roving. The filaments are usual ly made of glass or a polymeric material, and are characterized by high strength or ductility, or both. The treatment in this section will refer only to reinforcements of this kind, and will not include discussion of ferrocement, which one may include in the category of continuous reinforcement. The reinforcement in ferrocement is of a different nature, steel wire mesh, which is incorporated in a mortar matrix. This material is used for a variety of applications and its properties and application are documented quite well in several recent publications [26,27],...
