3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
Air entraining/plasticizing admixture
Admixture which increases workability, or allows water reduction, by incorporating during mixing a controlled
quantity 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.
3.3
Performance
Ability of an admixture to be effective in its intended use without detrimental effect.
3.4
Compliance dosage
The dosage of an admixture, expressed in % by mass of cement, stated by the manufacturer, which will meet the
requirements of this standard. 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 compliance 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 mortar admixtures, when sampled in accordance with EN 934-6, shall comply with the requirements in
table 1 using the test methods listed therein. Additional requirements specific to different types of mortar
admixtures are included in tables 2 and 3.
NOTE 1 Test should 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 (informative).
NOTE 2 For requirements necessary for CE-marking see Annex ZA.
