Abstract: This paper shows an application of SCC in Valencia (Spain), which consisted in building six columns of twelve metres in height at the north round / CV350 Crossroad Bridge. To avoid concreting joints and to minimise the construction time, constructors wanted to cast each column in one day. This fact, in addition to the high density of reinforcement, made impossible the concrete vibration by traditional methods.
Two important aspects were also considered: temperatures were higher than 25ºC with peaks up to 35ºC, and pressure limits on the formwork were never to be surpassed. The proposed solution was a 550–600 mm slump-flow SCC, with a grain size distribution similar to traditional concrete.
This paper describes the SCC features, the concrete mix design, prior tests, production, delivery and quality control.
