Arset Shot Series     TS EN 934-5 Table 2
ASTM C 1141 Type II
  • Increases early strength of concrete.

  • Low rebound.

  • Provides layer thickness up to 30 cm with one application.

  • Becomes easy overhead spraying because improved the bond of the shotcrete to the rock and 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
  • In tunnels

  • Ground and slope stabilization

  • Shotcrete applications with high early strength properties

  • In mining applications

Terms of Use

ARSET SHOT SERIES products are added through the appropriate shotcrete nozzle. The mixing of concrete and proper nozzle process is required. Fresh concrete properties must be appropriated according to the shotcrete equipment, capacity of the equipment, ambient temperature and other conditions.

Consumption Dosage

ARSET SHOT SERIES products are generally dosed at rates ranging from 2.5% to 8% by weight of cement. Dosages will vary depending on desired acceleration, ambient conditions and cement used. Use of alkali-free accelerators to attain very early initial set times will cause lower 28 day strengths to occur. For this reason, it is important to determine the lowest practical dose rate to attain desired acceleration.

Method of Application

The right dosing, mixing and nozzle operation is crucial for reaching the required shotcrete quality. For pumped concrete, maximum particle size (Dmax) is 8 mm water / cement ratio must be lower than 0,48. Suitable plasticizer should be used. Fresh concrete temperature should be over 15 °C.

Compatibility with Other Admixtures

ARSET SHOT 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 Zero Series


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

Shelf life is 6 months if stored in original unopened IBC tank or barrel packaging. In case of storage in bulk, it is 1 year provided that a circulation pump is used in the tank made of stainless steel.

Packaged products must be shaken before use.

If waiting for a long time, before using the product homogeneous by agitating, stirring or circulation pump make it. It cannot be stored in normal sheet containers.

Do not use soft steel tanks.

In case of storage in large volume tanks, a circulation system is required. 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.

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