EN934-2 water CE certification (concrete admixture EN934 certification)
Published：2024-5-7 14:05:15 Read：
EN934-2 water reducing agent EU CE certification & Nanjing SMART Company
Concrete water agent in the EU market needs to meet the EU compulsory CE certification requirements, water agent according to EN 934-2:2009+A1:2012 EU standard CE certification. Testing and certification according to the EU CPR regulations of construction products, and adding CE label, can be successfully sold in the EU market. Nanjing SMART Company is a domestic authorized cooperative organization of the EU Announcement number, which directly accepts the EN934-2 water-reducing agent CE certification, and provides one-stop service to reduce the intermediate links. Tel.: +86 25-8658 3475.
What is a water reducer?
Water reducing agent is a kind of concrete admixture which can reduce the mixing water consumption under the condition of maintaining the concrete slump. Most belong to anionic surfactants, lignin sulfonate, naphthalene sulfonate formaldehyde polymer, etc. Add concrete mixture to disperse cement particles, can improve its work, reduce unit water consumption, improve the fluidity of concrete mixture; or reduce the amount of unit cement, save cement.
EN934-2 water-reducing agent CE certification standard and scope of application
EN 934-2 dmixtures for concrete, mortar and grout - Part 2: Concrete admixtures - Definitions, requirements, conformity, marking and labelling
EN 934-2 specifies the definitions and requirements of admixtures used in concrete.
It includes admixtures for field mixing, ready-mixed plain concrete, reinforced concrete, and prestressed concrete and precast concrete.
The performance requirements in this standard are applicable to admixtures used in normal consistency concrete.
EN 934 Mortar concrete and cement slurry additives, consisting of the following parts:
EN 934-1: Common requirements
EN 934-2: Definition, requirements, standards, marking and labeling of concrete additives
EN 934-3: Definition, requirements, compliance, marking and labeling of masonry mortar additives
EN 934-4: Definition, requirements, compliance, marking and labeling of prestressed reinforcement cement slurry additives
EN 934-5: shotcrete definition, requirements, compliance, marking and labeling
EN 934-6: Sampling standard control and compliance assessment
This European standard can be used with EN480 series and EN 480 is part of the additive test method.
EN 934-2 water-reducing agent CE certification System
System 2+
Manufacturer''s responsibilities: Factory production control (FPC) plant production control; Initial type testing initial type test; Testing of samples taken at the factory plant sampling test
NB agency Responsibilities: Certification of FPC on the basis of Initial inspection of factory and of FPC, Continuous surveillance, assessment and approval of FPC based on initial inspection of the plant and its plant and ongoing supervision, evaluation, approval of FPC (FPC).
EN 934-2 key testing items of water-reducing agent
EN934-2 Table 2 Specific requirements for water reducing/plasticizing admixtures (at equal consistence)
Special requirements for water reduction / plasticizer admixtures (equal consistency)
EN934-2 Table 3.1 — Specific requirements for high range water reducing/super plasticizing admixtures (at equal consistence)
Special requirements for high-range water reduction / hyperplasticizing admixture (equal concentration)
EN934-2 Table 3.2 — Specific requirements for high range water reducing/super plasticizing admixtures (at equal w/c ratio)
