Self-compacting concrete in bridge construction on federal trunk roads

Several structures already built demonstrate the advantages of self-compacting concrete in constructing bridges. However, this can only be achieved by fulfilling the special requirements posed by this building material. The technological, logistical and economic expenditure involved in the production and processing of self-compacting concrete is pronounced compared to conventional vibrated concrete. Important criteria when estimating costs and benefits are the expected high quality of workmanship, elimination of noise and vibrations resulting from compaction, and selfacting consolidation and deaeration during the flow of self-compacting concrete over lengths of up to several metres, also through poorly accessible cavities.
