Performance

Product advantages

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.

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.

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.

Storage

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.
