Lyngby, Denmark ABSTRACT it seems that the use of SCC has Both filling and passing ability are 2 temporarily stagnated [Newsletter ]. One important properties to be considered for reason for the stagnation appears to be the self-compacting concrete. This paper segregation resistance of SCC, which is presents simulations of the L-box test and lower than that of conventional concrete. It corresponding experiments. The should be noted that the definition of SCC assumption of a continuum mechanical approach, where the fluid rheology is varies. described by the Bingham model, is tested. Other important properties are the filling and the passing ability
