4.1 Characteristics of composite material Glassfibre reinforced concrete is a composite material for which the glassfibre has the function of a reinforcement for the cementitious matrix. The properties of the composite material as manufactured depend on: a) the properties of the matrix as base; b) the properties, geometry, quantity and orientation of the glassfibre as reinforcement; c) the bond between matrix and glassfibre; d) the manufacturing processes; e) the conditions and the treatments during production (curing). 4.2 Composition of GRC
The mechanical properties of GRC depend on the mix design and shall be consistent with the product requirements. The mix designs in Table 1 are intended as a guide; mix designs falling outside these values may be acceptable if practical experience is available and the performance has been verified before use.
