The properties of GRC depend on: a) the constituent materials used; b) the composition of glassfibre reinfo

18、rced concrete; c) the production processes. The classification of GRC is based on the material properties that can be achieved. DIN EN 15191:2010-04 EN 15191:2009 (E) 5 1 Scope This European Standard deals with the classification of glassfibre reinforced concrete. This classification conforms to the

19、 needs of the design process of glassfibre reinforced concrete components. This European Standard applies only if EN 1169 is followed.
