Scope

This document specifies test methods applicable to Fiber-reinforced polymer (FRP) grids as reinforcement or pre-stressing tendons in concrete, including physical, mechanical, durability, long term durability and bond properties.

FRP grids in this standard can be used for rehabilitating existing RC structures and reinforcing new constructions.

FRP grids in this standard are made of fibre and resin matrix. Types of fibres are aramid fibre, basalt fibre, carbon fibre or glass fibre. The matrix includes thermosetting resins, such as vinylester, unsaturated polyester resins, as well as thermoplastic resins, including polypropylene, polyamides, and polymethyl methacrylate.

FRP grids in this standard are a rigid array of interconnected FRP bars, and do not include fiber textile and fabric with a mesh type.

In this standard, durability refers to alkaline resistance.
