Self-Compacting Concretes (SCC) are a special category of concretes and directions for designing formwork relative to ordinary concretes do not apply to them. In this paper an experimental study on formwork pressure exerted by SCC is reported. Behaviour of the SCC was investigated into instrumented formworks provided of two different type of pressure sensors: common diaphragm pressure transducers and dilatometer cells. In situ measurements of formwork pressure were carried on walls and concrete columns 6m and 9m high, 0.30m thick and 2.50 or 0.50m wide respectively. Successfully, both type of sensors were in agreement describing the continuous time variation of the pressures.

Abstract
Self-Compacting Concretes (SCC) are a special category of concretes and directions for designing formwork relative to ordinary concretes do not apply to them. In this paper an experimental study on formwork pressure exerted by SCC is reported. Behaviour of the SCC was investigated into instrumented formworks provided of two different type of pressure sensors: common diaphragm pressure transducers and dilatometer cells. In situ measurements of formwork pressure were carried on walls and concrete columns 6m and 9m high, 0.30m thick and 2.50 or 0.50m wide respectively. Successfully, both type of sensors were in agreement describing the continuous time variation of the pressures.Pubblicazioni consigliate
