(Main)Aggregates for mortar
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.

Diese Norm gilt nicht für Füller, die als Bestandteil von Zement oder als nicht inerte Füller für Mörtel verwendet werden sollen.
Sie enthält Festlegungen für die Bewertung der Konformität von Produkten nach dieser Europäischen Norm.
ANMERKUNG 1 Die Anforderungen dieser Europäischen Norm basieren auf Erfahrungen mit Gesteinskörnungsarten, die sich in der Anwendung bewährt haben. Die Verwendung von Gesteinskörnungen aus Bezugsquellen ohne eine derartige Bewährung, wie z. B. von rezyklierten oder in einem industriellen Prozess entstandenen Gesteinskörnungen, sollte sorgfältig geprüft werden. Derartige Gesteinskörnungen könnten trotz Übereinstimmung mit sämtlichen Anforderungen dieser Europäischen Norm Eigenschaften besitzen, die nicht im Mandat M 125 erfasst sind und die nicht für die Gesamtheit der Gesteinskörnungsarten mit einer bewährten Anwendung gelten. Falls erforderlich, können für die Beurteilung ihrer Eignung die am jeweiligen Verwendungsort geltenden Vorschriften herangezogen werden.
ANMERKUNG 2 Die Eigenschaften von leichten Gesteinskörnungen sind in prEN 13055-1 festgelegt.
