ARSTEP EXTRA 1000 Series

High Range Water Reducing / Superplasticizer Concrete Admixtures


ARSTEP EXTRA 1000 SERIES products are naphthalene sulfonate / lignosulfonate based high range water reducing / superplasticizer concrete additives used to increase the workability and mechanical properties of concrete by reducing the water / cement ratio. Summer (S) type products have the feature of delaying setting (consistency protection) in hot weather. Winter (W) type allows concrete casting in cold weather conditions. In addition, the products in this product group are also available in concentrated form (CONS). ARSTEP EXTRA 1000 SERIES products have more water cutting and consistency protection features compared to other sub- series groups.

ASTM C 494 Type F

  • Increases ultimate strength of concrete.

  • Improves workability of the concrete.

  • Decreases risk of segregation.

  • Extends the casting and placing time of concrete.

  • Provides smooth surface finish for concrete in the formwork without any segregation.

  • Prevents cold joints during concrete production with long casting time.

Areas of Use
  • Ready mixed concrete production (with or without pump)

  • Hot weather concreting

  • Long distance concrete transportation

  • Production of various types of concrete such as reinforced, unreinforced, light or normal concrete

  • Precast and precast concrete production

  • Mass concrete and roller compacted concrete applications

Terms of Use
  • ARSTEP EXTRA 1000 SERIES products are recommended to be added to the mixing water in ready-mixed concrete production plants. It should not be added directly to the dry mixture.
  • If it is added directly to fresh concrete, the mixing time should be extended for at least 1-2 minutes at fast speed to ensure sufficient homogeneity or this time should be determined in laboratory trials.
  • When more additives are used than the specified range of use, it may affect the setting time of the concrete. In such cases, a preliminary test should be done in the laboratory.

Usage according to weather conditions;

In Summer: Arstep Extra 1000 S     • In Winter: Arstep Extra 1000 W    • At Normal Temperature: Arstep Extra 1000

Consumption Dosage

ARSTEP EXTRA 1000 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

Aggregates and the binder (cement-silica fume-fly ash-blast furnace slag) should be mixed until obtaining a homogenous mixture. After adding 70% of mixing water into the dry mixture, ARSTEP EXTRA 1000 SERIES products should be added into the rest of water and should be mixed properly.

Compatibility with Other Admixtures

ARSTEP EXTRA 1000 SERIES products can be combined with the following admixtures. Laboratory tests should be carried out before use.

  • Arset Air Series
  • Arset Doz Series
  • Arset Friz Series
  • Arset Fast Series
  • Arset Retard Series
  • Arset Waterproof Series
  • Arset Zero Series


  • 30 kg plastic drum
  • 250 kg drum
  • 1000 kg container
  •  Bulk
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 it mechanically before using it.

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. ARSTEP EXTRA 1000 SERIES products are not flammable. For detailed safety information please consult the product’s Safety Data Sheet (SDS).
