  • ARSET VISCO admixture improves the viscosity of the concrete when used in concrete, prevents the cement and other fine components in the concrete from being washed away from the concrete, and ensures that a concrete that does not segregate in the water and does not dissociate in the water is prevented from penetrating into the concrete mass.

  • The use of ARSET VISCO when compared to an unused admixture concrete results since it reduces the strength of the concrete that is poured outdoors, but there is in an increase in strength in the concrete poured underwater, because it is also prevents washing and decomposition of the cement-mineral additive-fine aggregate.

  • The use of ARSET VISCO admixture does not change the workability time of the concrete in the short time (~ 45-60 minutes).

  • A trial should be made for a longer period.

  • The use of ARSET VISCO admixtures does not change the concrete normal setting time.

  • The chemicals it contains do not damage the fittings.

  • The chemicals it contains are alkaline resistant.

  • Can be used in fresh and saltwater environments.

  • Ensures good adhesion of cement and aggregate components in concrete.

  • Provides a well-pumpable, non-segregating, non dissipating concrete.

  • Increases resistance to chemicals.

  • Provides impermeability in concrete.

  • 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 obtaining concrete that does not decompose in underwater castings

  • As an additive in injection and grouting mortars

Terms of Use
  • Use with naphthalene sulfonate-based additives is not suitable.

  • Cement CEM I 42.5 and its dosage should be at least 360 kg.

  • The water / cement ratio should be between 0.40 and 0.45.

  • High performance, low water / cement ratio concrete and suitable high water reducer to achieve the required slump (18-25 cm), hyper plasticiser (DEGASET SERİES) should be used.

  • Air entraining additives may be used in the range of 4.0-6.0%.

  • Aggregate Dmax 16 mm past, fine aggregate, it should be 50-60%.

  • Mineral additive should be used up to 15% of cement.

Consumption Dosage

ARSET VISCO is used 0,5-2,0% of total binder. Where water flow is fast, it should be between 1.5-2.0%. It is necessary to test for the correct and optimum ratio.

Method of Application

Ready-mixed concrete plant: It is added to concrete components like traditional concrete admixture.

Usage in the truck mixer on the construction site: While turning the truck mixer, slowly add the ARSET VISCO mixture onto the ready-mixed concrete in the truck mixer and mix for at least 5 minutes before pouring the concrete.

Compatibility with Other Admixtures

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