Evolution of pressure generated by self compacting concrete on a vertical channel

The lateral and vertical pressure exerted on the formwork by the fresh self-compacting concrete (SCC) and its evolution in the time are data often unknown and thus difficult to control. In order to predict the variation of 10 SCC pressure over time, four flush diaphragm pressure sensors were used to measure concrete pressures on formwork. The test campaign aimed to determine the pressure exerted by the concrete on a vertical channel (post type) and to evaluate the impact of some rheology parameters, such as plastic viscosity, yield stress, slump flow diameter and V-Funnel flow time.
