摘要

This study concerns the prediction of lateral pressure exerted by self-compacting concrete (SCC) on formwork during the casting process. This estimation is obtained using Janssen's model as used in the statics of ensiled granular material. The model has been adapted to SCC. The friction coefficient between the concrete and the wall occurring in the model is measured with a new type of tribometer. The case of SCC placed in 12 m high formwork by three companies using two different techniques is presented. Comparison of the predicted results with on site measurements shows good agreement.
