^AЦ?IO^AЁ?Ь?^И?Й? AGGREGATES FOR MORTAR

1 1 Scope
This European Standard specifies the properties of aggregates and filler aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates for use in mortar, e.g.,
a) masonry mortar,
b) floor/screed mortar,
c) surfacing of internal walls (plastering mortar), d) rendering of external walls,
e) special bedding materials,
f) repair mortar,
g) grouts,
for buildings, roads and civil engineering works.
This standard does not cover filler aggregates to be used as a constituent in cement or as other than inert filler aggregates for mortars or aggregates to be used in the surface layer of industrial floors.
It provides for the evaluation of conformity of the products to this European Standard.
NOTE 1 Aggregates used in construction should comply with all the requirements of this European Standard. As well as familiar and traditional natural and manufactured aggregates Mandate M/125 "Aggregates" included recycled aggregates and some materials from new or unfamiliar sources.
Recycled aggregates are included in the standards and new test methods for them are at an advanced stage of preparation. For unfamiliar materials from secondary sources, however, the work on standardisation has only started recently and more time is needed to define clearly the origins and characteristics of these materials. In the meantime such unfamiliar materials when placed on the market as aggregates must comply fully with this standard and national regulations for 2 ^ EN 932-1 EN 932-5 EN 933-1 EN 933-3 EN 933-7 EN 933-8 EN 933-9 dangerous substances depending upon their intended use. Additional characteristics and requirements may be specified on a case by case basis depending upon experience of use of the product, and defined in specific contractual documents."
NOTE 2 Properties for lightweight aggregates are specified in EN 13055-1:2002

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1 aggregate
granular material used in construction. Aggregate may be natural, manufactured or re-cycled
3.2 natural aggregat e
aggregate from mineral sources which has been subjected to nothing more than mechanical processing
3.3 manufactured aggregate
aggregate of mineral origin resulting from an industrial process involving thermal or other modification
3.4 recycled aggregate
aggregate resulting from the processing of inorganic material previously used in construction
3.5 3.6 3.7 3.8 3.9 ^ 3.10 3.11 3.12 3.13 3.14 3.5 aggregate size
designation of aggregate in terms of lower (d) and upper (D) sieve sizes expressed as d/D.
3.6 coarse aggregate
designation given to the larger aggregate sizes with D greater than or equal to 4 mm and d greater than or equal to 2 mm
3.7 fine aggregate
designation given to the smaller aggregate sizes with D less than or equal to 4 mm.
NOTE Fine aggregate can be produced from natural disintegration of rock or gravel and/or by the crushing of rock or gravel or processing of manufactured aggregate
3.8 fines
particle size fraction of an aggregate which passes the 0,063 mm sieve
3.9 filler aggregate
aggregate, most of which passes a 0,063 mm sieve, which can be added to construction materials to provide certain properties.
NOTE See 3.8 for the definition of "fines"
3.10 particle size fraction
Fraction on the aggregate passing the larger of two gieves and retained on the smaller
NOTE The liower limit can be zero
3.11 oversize
Part of the aggregate retained on the larger of the limiting sieves used in the aggregate size discription
3.12 undersize
part of the aggregate passing the smaller of the limiting sieves used in the aggregate size discription
3.13 category
level ofa property of an aggregate expressed as a range of values or a limiting value.
NOTE There is no relationship between the categories of different properties
3.14 grading
particle size distribution expressed as the percentages by mass passing a specified set of sieves
NOTE This designation accepts the presence of some particles which are retained on the upper sieve (oversize) and some which pass the lower sieve (undersize).
