In Sweden, the market share of cast-in-place Self-Compacting_x000D_ Concrete (SCC) is only around 10%. Uncertainty concerning_x000D_ formwork pressure is considered to be one of the most important_x000D_ factors explaining the slow progression. During construction of a_x000D_ 400 m long, 6 m high and 0.27 m thick prison wall in northern_x000D_ Sweden, SCC alone was used. The formwork used consisted of_x000D_ steel-framed panels, instrumented with flush-mounted pressure_x000D_ sensors. Each concrete batch was tested for air content, slumpflow,_x000D_ concrete and air temperature. Besides tests on torsional_x000D_ moment or torque, L-box, and V-funnel were carried out._x000D_ Relations between concrete properties, casting rate and time_x000D_ versus formwork pressure were investigated. The results_x000D_ confirmed that structural build-up of SCC has to be taken into_x000D_ account for predicting formwork pressure. The torsional moment_x000D_ was measured at three consecutive times at each casting and the_x000D_ time-dependent development of the torsional moment was_x000D_ subsequently used as indirect input in two simple formwork_x000D_ pressure methods that have been developed recently. The_x000D_ comparison between computed and measured formwork pressure_x000D_ shows that both these methods would be possible to use for_x000D_ predicting formwork pressure generated by SCC.
