ABSTRACT

Glass fibre reinforced cementitious composites have been developed mainly for the production of thin sheet components, with a paste or mortar matrix, and ~5% fibre content.1 Other applications have been considered, either by making reinforcing bars with continuous glass fibres joined together and impregnated with plastics,2 or by making similar short, rigid units, impregnated with epoxy, to be dispersed in the concrete during mixing.3 In practice, however, the main application of the glass fibre reinforcement is in thin sheets, and this will be the focus of this chapter. Such systems are referred to in Europe as GRC (glass fibre reinforced cement), while in the USA the term GFRC (glass fibre reinforced concrete) was adopted.
