Arset Retard Series     TS EN 934-2 Table 8
ASTM C 494 Type B
  • Ensures controlled prolongation of setting of concrete.

  • Does not have adverse effects on final strengths.

  • Reduces creeping and contraction.

  • Increases workability.

  • Minimizes the effects of temperature.

  • Reduces segregation and bleeding of concrete.

  • Ensures easy pumping.

  • Prevents the concrete from losing its viscosity fast, provides for extended viscosity protection depending on the type of cement used.

  • Prevents shrinkage cracks that may result from high hydration temperatures.

  • Do not contain chloride or any other components that result in corrosion in the reinforcements. Therefore, it is suitable for use in reinforced concrete structures.

Areas of Use
  • In case the concrete is transported over a long distance; in case of pouring large volumes of concrete (mass concrete) and preventing cold joints

  • In high temperature concrete casting

  • In long-wait concrete casting

  • In thin-reinforced reinforced concrete productions with placement difficulties

  • In the production of concrete where impermeability is required

  • It is used in places that will be subject to vibration again

  • It is used to compensate the loss of consistency in hot, windy and humid weather

Terms of Use
  • Concrete components may differ by their structures. The admixture to be added into the mixture to prevent segregation of the concrete should be applied in the suitable doses. Prior tests should be performed to check whether the admixture is suitable for the design of a certain concrete.

  • In case of using the admixture in the amount exceeding the specified use range, the setting time of the concrete may be prolonged. In such cases, the concrete should be kept humid to allow for curing until it hardens.

  • ARSET RETARD SERIES products must not be used with setting / hardening accelerator admixtures (Arset Fast Series or Arset Friz Series).

Consumption Dosage

ARSTEP RETARD SERIES products’ dosage should be adjusted according to the total amount of binder in the mixture design. This ratio varies according to the cement, aggregate, mineral additive, water components used in concrete mixture design and also the desired fresh and hardened concrete properties. Therefore, before determining the usage rate, laboratory tests should be made according to the properties expected from fresh and hardened concrete and the mixing ratio should be determined according to these tests.

Method of Application

ARSET RETARD SERIES products may be added with the mixing water or simultaneously during the mixing water is introduced to the concrete. It can also be added to the fresh ready mix concrete at the concrete plant or construction site.

Compatibility with Other Admixtures

ARSTEP RETARD SERIES products can be combined with the following admixtures. Laboratory tests should be carried out before use.

  • Arstep / Arstep Extra/ Degaset Series admixtures
  • Arset Air Series
  • Arset Doz
  • Arset Zero Series


  • 30 kg plastic drum
  • 250 kg drum
  • 1000 kg container
Storage and Shelf Life

Shelf life is 12 months from the date of production when stored in original unopened and undamaged packages (drums, barrels, IBC containers) at temperatures between +5 °C and +35 °C, protecting from direct sunlight, excessive heat and frost.

If the product has waited for a long time, make it homogeneous by mixing slowly at low speed with mechanical methods before using the product.

Make sure that the product does not freeze. If the product freezes, it should be thawed by keeping it at room temperature without using direct heat and mixed by mechanical methods until it becomes homogeneous.

Safety Measures

Use protective clothes, gloves, glasses and mask compatible with health and safety regulations during the application. Avoid direct contact with eyes and skin during storing and application, in case of contact wash off thoroughly with soap and water, if ingested seek medical attention immediately. Store away from all foodstuffs. Keep away from children. ARSET RETARD SERIES products are not flammable. For detailed safety information please consult the product’s Safety Data Sheet (SDS).
