Foreword
This document (prEN 15191:2005) has been prepared by Technical Committee CEN/TC 229 “Precast
concrete products”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.

Introduction
This standard deals with the properties of GRC depending on the constituent materials, the composition of
glassfibre reinforced concrete and the production processes. The glassfibre reinforced concrete (GRC) can be
manufactured using different combination of materials to meet the required properties. Mix composition, type
of cement, and the proportion, length and orientation of glassfibres may all be varied to produce a specific
product. A polymer dispersion may be used for curing purposes.
The classification is based on the material properties to be achieved.

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 the standard EN 1169 is followed.
This standard does not include the design methods.

3 Definitions and abbreviations
3.1 Terms and definitions
For the purposes of this standard, the following definitions apply:
3.1.1
additive
product that may be added by volume to the matrix composition to improve some properties. It can be reactive
(e.g. silica fumes) or inert, mineral or organic (e.g. polymer dispersions)
3.1.2
admixture
product added in quantity less than 5% by volume (or the mass of cement), before or during mixing and giving
expected modifications to the initial properties (e.g. plasticiser, air entraining agents)
3.1.3
AR glassfibre
a glassfibre product with a proven resistance (prEN XXXX) to the alkaline environment of matrices made from
hydraulic cement
3.1.4
basic strand
glassfibre obtained by stranding a number of filaments (typically 100 to 200) having a defined individual
diameter (typically 10 µm to 30 µm)
3.1.5
roving
a 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 of hydraulic binder reinforced with glassfibres, these materials being
compatible
3.1.7
matrix
composition of the glassfibre reinforced concrete without the fibres. It is made of the mixture of sand, cement,
water an any additives and admixtures
3.1.8
spray processes
processes whereby continuous glassfibre are cut into set lengths and sprayed together with the matrix. The
processes are designed to give a glassfibre reinforced concrete in which the fibres are oriented parallel to the
mould surface
3.1.9
premix processes
processes whereby chopped strands of glassfibres are blended with the matrix to make a glassfibre reinforced
concrete ready for processing. The processes may be: “casting and vibration”, wet or dry spraying,
