EN 15191:2009 – Precast concrete products – Classification of glassfibre reinforced concrete performance
1 Scope
This European Standard deals with the classification of glassfibre reinforced concrete. This classification conforms to the needs of the design process of glassfibre reinforced concrete components. This European Standard applies only if EN 1169 is followed.
This standard does not deal with design methods.

3 Definitions and abbreviations
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
addition
product that may be added by weight or volume/weight to the matrix composition to improve some properties
NOTE 1 An addition can be reactive or inert, mineral or organic.
NOTE 2 Silica fumes are reactive and polymer dispersions are organic.
3.1.2
admixture
product added in quantity less than 5 % by weight), before or during mixing and giving expected modifications to the initial and final properties
NOTE The quantity of admixture is related to the mass of cement. The properties are for example: workability, air content.
3.1.3
AR glassfibre
glassfibre product with a proven resistance to the alkaline environment of matrices made from hydraulic cement
3.1.4
basic strand
glassfibre obtained by stranding a number of filaments having a defined individual diameter
NOTE Number of filaments: typically 100 to 200; individual diameter: typically 10 µm to 30 µm.
3.1.5
roving
number of parallel strands wound together on a mandrel to form uniform cylindrical package size
3.1.6
glassfibre reinforced concrete
GRC
composite material consisting of a matrix reinforced with glassfibres, these materials being compatible
3.1.7
matrix
part of GRC which is not fibres, normally composed of sand, cement, water and any additions and admixtures
3.1.8
spray process
process whereby continuous glassfibres are cut into set lengths and sprayed together with the matrix
NOTE The processes are designed to give a glassfibre reinforced concrete in which the fibres are oriented parallel to the mould surface.
