This document defines the general processes, procedures and rules for production and production control of Glass fibre Reinforced Concrete used to manufacture products commonly used in construction, civil engineering, architecture and other applications. Glass fibre reinforced concrete can be produced from a range of mix designs comprising various materials and manufactured by different processes. This document covers two primary production processes, namely Sprayed GRC and Premix GRC. This document does not cover concrete, where the glass fibre does not act as primary reinforcement but is used as an additive. It does not cover but can be used as guidance for injection and extrusion manufacturing processes.
