Ciria Report 108 Concrete Pressure On Formwork __hot__ Guide

The report became an instant reference for structural engineers, formwork suppliers, and concrete contractors worldwide.

: Currently considered a standard reference in the UK and internationally, often cited alongside standards like BS 5975 . The CIRIA 108 Calculation Model

Consider time-dependent load cases: Check formwork both for the peak pressure during casting and for reduced pressures as concrete sets; bracing and ties must resist transient peak loads. The report became an instant reference for structural

CIRIA Report 108 provided a semi-empirical method for calculating pressure. It moved away from the "worst-case scenario" of hydrostatic pressure and introduced a formula based on observed site behaviors. A graph showing "Lateral Pressure (kN/m²)" on the

Today, CIRIA Report 108 is considered the "authoritative official UK guidance on formwork". Its influence, however, extends far beyond the UK, as it is used as a fundamental reference and standard across the global construction industry alongside other major codes like ACI 347 (American), GB50666 (Chinese), and DIN 18218 (German).

I can provide more detailed structural guidance on this topic if you tell me:

Structural collapse or bursting of the shutters due to underestimating the pressure.
