26、9+A1:2012 (E) 4 1 Scope This European Standard defines and specifies the requirements and conformity criteria for admixtures for use in cement based masonry mortar. It covers two types of admixtures, long term retarding and air entraining/plasticising which are used in ready-mixed and site made maso
27、nry mortars. Provisions for the use of admixtures for masonry mortar are not part of this European Standard but are covered by EN 998-1 and EN 998-2. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the editi
28、on cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

33、tity of small, uniformly distributed air bubbles which remain after hardening 3.2 set retarding admixture for long term retarded masonry mortar set retarding admixture as defined in EN 934-2 but specifically intended for use in long term retarded mortar incorporating entrained air DIN EN 934-3:2012-

35、. The compliance dosage is within the recommended range of dosage 3.5 recommended range of dosage dosages between limits, expressed in % by mass of cement, which the manufacturer recommends for the product based on experience on site NOTE The use of the recommended dosage does not imply that complia
36、nce with this standard will be achieved over the whole range. Trial tests should be carried out with the materials to be used on site, to find the dosage necessary to achieve the required result. 3.6 maximum recommended dosage upper limit of the recommended range of dosage 4 Requirements Masonry mor
37、tar admixtures, when sampled in accordance with !EN 934-6:2001 and EN 934-6/A1:2005“, shall comply with the requirements in EN 934-1:2008, Table 1 using the test methods listed therein and the additional requirements specific to different types of admixture listed in Table 1 !below“. NOTE 1 Tests sh
38、ould be carried out with the admixtures and other materials intended to be used in the mortar to check whether the desired effect can be obtained. For content of substances and release of substances from the hardened mortar which are dangerous to health, hygiene and the environment see Annex A (info
