Corrosion Inhibiting Admixture


ARSET CORROSTOP is an additive material consisting of organic and inorganic materials that slows down the formation of corrosion in the reinforcement in concrete. Thanks to the efficiency of the components in the additive material, the molecules dissipate and cover the pores in the concrete, at the same time they form a protective layer that prevents corrosion by covering the steel reinforcement. Depending on the structure of the concrete, it shows properties that slow down or prevent corrosion.

Arset Corrostop     ASTM C 494 Type C    
  • Extends the life of concrete.

  • It extends the life of the reinforcement by preventing aggressive chemicals and moisture that may damage the steel reinforcement.

  • It does not contain chlorine.

Areas of Use
  • In all types of reinforced concrete

  • In precast concrete

  • In prestressed concretes

  • In foundation concretes

  • In retaining walls

  • In parking lots

  • In bridges and tunnels

  • In marine structures

  • In concrete that will be affected by aggressive environments

Terms of Use

In order for the concrete to be protected against corrosion by using ARSET CORROSTOP to be successful, the following issues should be considered;

  • It should have a low water / cement ratio.

  • There should be sufficient concrete thickness around the reinforcement.

  • The chlorine content in the concrete should be low.

  • Concrete should be well placed and compacted.

ARSET CORROSTOP can act as a set accelerator in concrete. Therefore, trials should be done before use, especially in hot weather, it may be necessary to reinforce with set retarding additives to prevent slump loss.

When used at high rates, it can reduce the amount of air in the concrete at a small rate. Therefore, the use of additional air entraining additives may be required.

Consumption Dosage

It is used at a rate of 2.0 - 6.0% of the total amount of binder. Optimum utilization rate should be determined according to laboratory trials.

Method of Application

ARSTEP CORROSTOP is added to the concrete mixture after 70% of the mixing water is used.

Since ARSET CORROSTOP contains water and the addition of admixture will increase the total concrete water / cement ratio, the concrete mixture water should be reduced in the ready-mixed concrete plant and the mixture design should be done accordingly.

Compatibility with Other Admixtures

ARSTEP CORROSTOP 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 Series
  • Arset Retard Series
  • 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.

Some subsidence may occur during long-term storage. In this case, the product can be used by filtering. Make sure that the product does not freeze.

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 CORROSTOP is not flammable. For detailed safety information please consult the product’s Safety Data Sheet (SDS).
