Self-compacting concrete - hardened material properties and structural behaviour

Self-compacting concrete (SCC) is an innovative construction material with a favourable rheological behaviour, which is caused in the modified concrete composition. Based on this fact SCC offers improved properties and therefore many advantages regarding the productivity and the design potential compared with normal vibrated concrete. Consequently, the amount of SCC, used for structural purposes has strongly increased. In this context it has to be clarified, if it is possible to apply the current design rules, e.g. Model Code 90 and Eurocode 2, based on years of experience on normal vibrated concrete, to structural members made of SCC as well. This paper represents the analysis of own and internationally published test results of the compressive strength, tensile strength, modulus of elasticity, bond behaviour as well as the time-dependent deformations of SCC in comparison with conventional concrete, in order to give a general statement regarding the agreements and differences between the hardened material properties of these concretes.
