Arset Fast Serisi     TS EN 934-2      
  • Depending on the cement type and concrete temperature, it significantly increases early strength of concrete in the first 24 hours.

  • It accelerates the hydration reaction of cement in cold weather and provides concrete to set early.

  • Reduces mold release time.

  • Protects concrete from freezing.

  • Does not contain chloride or any other components that will result in corrosion of the reinforcement. Suitable for use in any reinforced concrete structures.

  • 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
  • For concrete production where very high early strength is required

  • Concrete production in cold weather

  • Where frost effect is expected

  • When sudden temperature drop is expected

  • Multi-reinforced concrete

  • In ready-mix concrete, in pouring precast and prefabricated concrete

  • Where it is necessary to mold early or load the molds quickly

  • It can be used in combination with normal and superplasticizers however using in combination with admixtures that have retarding effect is not recommended

Terms of Use

When pouring concrete in cold weather, the following issues should be considered:

  • Aggregate, water and cement should be stored under suitable conditions to prevent the effects of cold.
  • Instead of blended cement, cements with high clinker ratio should be preferred.
  • The formwork and reinforcement should be protected against water, snow and icing. If necessary, ice and water should be removed by heating before concrete casting.
  • Molds should be isolated.
  • Fresh concrete temperature should be at least 5-15 °C. Concrete should be covered to prevent heat and moisture loss and should be well protected until it reaches 4-5 N/mm2 pressure resistance.
  • ARSET FAST SERIES products must not be used with set retarder admixtures (Arset Retard Series).
Consumption Dosage

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