1 Scope
This European Standard specifies definitions and requirements for admixtures for use
in concrete.
It covers admixtures for plain, reinforced and prestressed concrete which are used
in site mixed, ready mixed concrete and precast concrete.
The performance requirements in this standard apply to admixtures used in concrete of normal consistence.
They may not be applicable to admixtures intended for other types of concrete such
as semi-dry and earth moist mixes.
Provisions governing the practical application of admixtures in the production of
concrete, i.e. requirements concerning composition, mixing, placing, curing etc. of
concrete containing admixtures are not part of this standard.
