This document specifies test methods for identifying the performance of a glassfibre reinforced concrete (GRC) composition in terms of bending strength, water absorption, dry density and dimensional variations. These methods can be used for type testing or for the evaluation of the uniformity of the production process. They can be used on GRC coupons prepared as described in this document, or on samples cut out of GRC products. NOTE A test to assess the influence of time on the mechanical properties (i.e. LOP and MOR) is described for information in Annex C. Other methods can be found in scientific literature.
