These presentations will report on the latest information regarding the measurement of lateral pressure exerted by self-consolidating concrete (SCC). Examples include extensive field studies carried out on shear walls, column, and wall elements in building construction and infrastructure rehabilitation projects. Comparison between field measurements and various design models, including those proposed in ACI 347, CSA A23.1, and DIN, will be highlighted. Fresh concrete properties affecting formwork pressure and the decay in pressure until pressure cancelation are highlighted, and new test methods that can be used to evaluate these characteristics are illustrated.
