: Currently considered a standard reference in the UK and internationally, often cited alongside standards like BS 5975 . The CIRIA 108 Calculation Model
That’s where comes in. Despite being nearly 40 years old, it remains the gold standard guidance for calculating lateral pressure on vertical formwork in the UK and beyond. ciria report 108 concrete pressure on formwork
CIRIA 108 assumes internal vibration is stopped 1.5m below the current concrete level. If you over-vibrate (running the head too deep), you liquify the stiffened concrete, resetting the pressure to hydrostatic at that depth. : Currently considered a standard reference in the
