This paper presents the experimental results of a study on large-scale confined
self-compacting concrete columns; this study is part of a wide national research
programme regarding the behaviour of self-compacting concrete and the structural
effects due to its utilization.
The examined variables have included concrete type (self-compacting (SCC) and
vibrated rheoplastic concrete (RpC)) - compressive strength being the same (class
C45/50) - and volumetric ratio of transverse steel reinforcement.
SCC is mainly used when a great fluidity is requested (for example high steel
reinforcement percentage), condition where usually a RpC is preferred.
The results show that when a SCC is used instead of high flowability concrete, both
the material and the structural behaviour are on average similar; frequently a greater
scatter of the experimental quantities distinguishes the results of the tests on SCC
