Striking of Formworks


Factors to be considered prior striking formworks (CIRIA Report 136):

  • Collapse
  • Deflection
  • Freeze/thaw damage
  • Mechanical damage
  • Further damage due to site operations
  • Moisture loss
  • Color variation
  • Durability
  • Thermal cracking and shock
  • Site requirements

Minimizing striking times is generally calculated by determining the cube strength required to satisfy all the criteria.
