Method Statement for Permanent Post Tensioning

According to the site conditions (temperature, humidity), the constituents of the grout have to be in good conditions during production and injection: • During grouting, the maximum grout temperature is limited to 32 °C. If necessary, water shall be chilled using ice cube. • Cement shall not be exposed to sunlight. It should not be younger than a week, and not older than 6 months. No lump shall be present inside the bag.

Method Statement for Post Tensioning Friction Test

INTRODUCTION General The purpose of this procedure is to determine the actual friction coefficient and wobble coefficient which shall be used in the strand elongation calculation of the post tensioning works. Scope of work To determine friction and wobble coefficient to be used in the elongation calculation, a friction test shall be performed prior to the first stressing operations on site.
