Ciria Report 108 Concrete Pressure On Formwork Jun 2026

Have a ready-mix engineer track the concrete temperature. If the truck arrives cooler than expected, recalculate P_max immediately.

Introduction CIRIA Report 108, titled Concrete Pressure on Formwork , is a cornerstone document in structural and temporary works engineering. Published by the Construction Industry Research and Information Association (CIRIA) in 1985, this report revolutionized how engineers calculate the lateral pressure exerted by fresh concrete on vertical formwork faces. ciria report 108 concrete pressure on formwork

Pmax=C1Rcap P sub m a x end-sub equals cap C sub 1 the square root of cap R end-root (Where C1cap C sub 1 Have a ready-mix engineer track the concrete temperature

, strict monitoring must ensure the placing crew does not accelerate to Do you need a using the CIRIA equations

The generalized CIRIA 108 equation for the maximum pressure blanketing the lower portion of the formwork is:

Nearly 40 years after its publication, remains the gold standard for rational formwork design. It shifted the industry from fearful over-design to intelligent, risk-aware engineering.
