fot3Supervision during post-tensioning of the tank wall of ammonia storage facility in Zakłady Azotowe Puławy S.A.

Reinforced concrete tank wall post-tensioned with circumferential internal tendons in Zakłady Azotowe Puławy S.A. . The tank is intended for storage of ammonia with a temperature up to -40 degrees.

Within the supervision were carried out experimental tests that form the basis for the evaluation of the effectiveness in realization of design assumptions.
Scope of work included:

  • estimation of basic mechanical properties of concrete of tank wall
  • measurement of radial displacements of tank wall during post-tensioning
  • measurement of changes in opening of vertical structural connections on the height of the first peripheral segment of the tank wall
  • measurement of changes in opening of horizontal structural connection localized between the first and second segment of the tank wall
