Ready Mix – Precast

Admixture Scales

Additive Scale PR-AS-3

  • Suited for dosing up to three (3) different additives in the same scale.
  • Weighing cylinder made of acryl glass or stainless steel.
  • The cylinder is placed between two special flanges made by Ertalon (high strength cast nylon) and it is suspended from one load cell. Thanks to the innovative stabilizing brackets that are holding the cylinder from the flanges, the weighing accuracy is not affected by vibrations, air, etc.
  • Capacity 40Lt in volume or about 50Kg weight of additives.
  • Static weighing accuracy is ± 20 gr across the scale’s capacity.
  • All parts of the scale that come in contact with the additives are either plastic or stainless steel providing maximum corrosion resistance.
  • Built-in rinsing circuit with a solenoid valve and a water filter.
  • Integrated water trap with pressure regulator for suppling pressured air in to the scale. A pressure switch signalizes valve status (open-closed).
  • Gravity discharge through a 1” squeeze valve.
  • A discharge pump can be optionally added to assist in discharging

Additive Scale PR-AS-4X20

  • Suggested for dosing of additives that cannot be mixed.
  • The weighing bin has four (4) separate stainless steel compartments
  • Capacity of approximately 4 x 20 Lt in volume or about 100 kg weight of additives.
  • The tank is suspended from two load cells and is not affected by vibration, air, etc.
  • The accuracy of static weighing is ± 30 gr across the scale’s capacity.
  • All parts of the scale that come in contact with the additives are either plastic or stainless steel providing maximum corrosion resistance.
  • Each compartment has an individual rinsing circuit with a separate electrovale and a common water filter.
  • The discharging of each compartment is done very quickly with gravity flow through a 1" pinch valve. The additives supplies are connected to nozzles.
  • Integrated water trap with pressure regulator for connecting the scale to the air circuit.
  • A pressure switch signalizes valve status (open-closed).
  • Optionally, a discharge pump can be installed in one or all of the compartments.

Additive Scale PR-AS-6

  • Suited for dosing up to six (6) different additives in the same scale.
  • Weighing chamber made of stainless steel.
  • The chamber is suspended from two beam type load cells.
  • Capacity 60Lt in volume or about 75Kg weight of additives.
  • Static weighing accuracy is ± 30 gr across the scale’s capacity.
  • All parts of the scale that come in contact with the additives are either plastic or stainless steel providing maximum corrosion resistance.
  • Built-in rinsing circuit with a solenoid valve and a water filter.
  • Integrated water trap with pressure regulator for suppling pressured air in to the scale. A pressure switch signalizes valve status (open-closed).
  • Very fast gravity discharge through a 2” squeeze valve.
  • A discharge pump can be optionally added to assist in discharging

More and more admixtures

It is clear that over the last decade, more and more chemical additives have been used in concrete. They should be used with extreme caution in order to accurately measure the amounts specified in the recipes.
