Ciria Report 108 Concrete Pressure On Formwork 【360p】

CIRIA Report 108 (1985) serves as the UK industry-standard guide for calculating lateral concrete pressure on formwork, utilizing a semi-empirical formula that accounts for placement rate, concrete density, and temperature. The report distinguishes between wall and column pressures and covers the impact of modern admixtures, though it may be conservative for highly flowable self-compacting concrete. The report is available through the CIRIA bookstore . Concrete pressure on formwork (R108) - CIRIA

Consider "horizontal layering" (pouring in lifts of 1-2 meters with a 30-minute delay between lifts). This allows lower layers to set, drastically reducing pressure on the bottom tie-rods. ciria report 108 concrete pressure on formwork

In the world of construction, few forces are as misunderstood—or as dangerous—as fresh concrete pressure on formwork. Every year, projects face blowouts, bulging forms, and even catastrophic failures because engineers and contractors underestimate the liquid-like pressure exerted by newly placed concrete. For decades, the industry struggled with inconsistent guidelines until a groundbreaking document changed everything: CIRIA Report 108 (1985) serves as the UK

Published in 1985, CIRIA Report 108 (R108) serves as a primary industry standard for calculating the lateral pressure of fresh concrete on formwork. The report provides an empirical formula to determine maximum pressure based on variables like concrete density, rate of rise, and temperature, which remains relevant for ensuring safe, cost-effective formwork design.

In the world of concrete construction, few elements are as critical—and as often misunderstood—as lateral pressure on vertical formwork. Over-pour a wall or misjudge the setting rate of a column, and the result is a blowout: thousands of dollars in wasted material, potential worker injury, and crippled project timelines.

The report’s most influential contribution is the formula for maximum lateral pressure (P_max) at the base of a vertical form:
