Aggregates for mortar

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   The requirements in this European Standard are based upon experience with aggregate types with an established pattern of use.  Care should be taken when considering the use of aggregates from sources with no such pattern of use, e.g., recycled aggregates and aggregates arising from certain industrial by-products.  Such aggregates, which should comply with all the requirements of this European Standard, could have other characteristics not included in Mandate M 125 that do not apply to the generality of aggregates types with an established pattern of use and when required, provisions valid at the place of use can be used to assess their suitability.
NOTE 2   Properties for lightweight aggregates are specified in prEN 13055-1.

EN 13139:2002 (E)12The presence of organic matter shall be determined in accordance with EN 1744-1:1998, 15.1 (sodium hydroxidetest).

If the results indicate the presence of humic acid, the presence of fulvo acids shall be determined inaccordance with EN 1744-1:1998, 15.2.

If the supernatant liquid in these tests is lighter than the standard coloursthe aggregates shall be considered to be free from organic matter.NOTE 1Some inorganic compounds which discolour the supernatant liquid in the sodium hydroxide test do not adverselyaffect the setting and hardening of mortar.NOTE 2Sugars do not affect the colour of the supernatant liquid in the sodium hydroxide test or the fulvo acid test.

If it issuspected that sugars or sugar type materials are present, the aggregate should be tested using the mortar specimen test (seeEN 1744-1:1998, 15.3). The stiffening time and compressive strength requirements shown above should apply.When required the presence of lightweight organic contaminators shall be tested in accordance with EN 1744-1:1998,14.2 and the results declared.7.5 Additional requirements for manufactured aggregates7.5.1 Water soluble matterWhen determined in accordance with EN 1744-1:1998, clause 16, water soluble matter shall not exceed 1 % bymass.7.5.2 Loss on ignitionWhen required, the loss on ignition determined in accordance with EN 1744-1:1998, clause 17, shall not exceed thelimits specified in Table 6.Table 6 — Limits for loss on ignitionLoss on ignition (by mass)Air cooled blast furnace slag%Pulverized fly ash (pfa)%35 aa

A loss on ignition of 7 % may be
tolerated at the place of use depending upon the environmental class to

which the structure is exposed.7.6 Durability7.6.1 Alkali-silica reactivityWhen required the alkali-silica reactivity of aggregates and filler aggregates shall be assessed in accordance withthe provisions valid in the place of use and the results declared.NOTEGuidance on the effects of alkali-silica reactivity, is given in annex D.8 Evaluation of conformity8.1 GeneralThe producer shall undertake initial type tests (see 8.2) and factory production control (see 8.3) to ensure that theproduct conforms to this European Standard and to declared values as appropriate.

EN 13139:2002 (E)138.2 Initial type testsInitial type tests relevant to the intended end use shall be carried out to check compliance with specifiedrequirements in the following circumstances:a)a new source of aggregates is to be used;b)there is a major change in the nature of the raw materials or in the processing conditions which may affect

the properties of the aggregates.The results of the initial tests shall be documented as the starting point of the factory production control for thatmaterial.

This shall particularly include the identification of any components likely to emit radiation above normalbackground levels, any components likely to release polyaromatic carbons or other dangerous substances. If thecontent of any of these components exceeds the limits in force according to the provisions valid in the place of useof the aggregate, the results of the initial tests shall be declared.8.3 Factory production controlThe producer shall have in place a system of factory production control that complies with the requirements ofannex E.The records held by the producer shall indicate what quality control procedures are in operation during theproduction of the aggregate.NOTEThe form of control applied to any aggregate depends upon its intended use and the regulations relating to that use.9 Designation and description9.1
