Over deze norm
This European Standard specifies the common requirements for all admixtures covered by EN 934-2, EN 934-3, EN 934-4 and EN 934-5 and which contain the specific requirements for each type of admixture. The requirements for corrosion behaviour are not applicable to chloride based admixtures ontaining embedded metal. The requirements for corrosion behaviour in this standard include an approved list and a declared list of active substances used in some admixtures. These lists are based on experience which shows that the use of admixtures only containing substances on the approved list do not promote the corrosion of embedded steel. Materials on the declared list are subject, in some countries, to national restrictions on their use for certain applications and therefore have to be declared on the CE mark.
