Computational Segregation Analysis During Casting of SCC
Abstract Uneven aggregate distribution can increase the local porosity and thus the permeability of concrete. Varying content of mortar causes heterogeneous shrinkage and creep in a given element. Moreover, high heterogeneity will increase the probability that these phenomena yield high internal stress gradients and thus cracking. In this work, a status is given about the development of a concrete casting solver within the OpenFOAM framework that can calculate the coarse aggregate distribution as a function of time. The aim is to predict the effect of segregation by gravity as well as by the shear rate induced particle migration. Case examples show that the latter can play a very important role in affecting the aggregate variation within a concrete element.
