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.
