After the first introductory chapter dealing with the various physical phenomena involved in flows of fresh cementitious materials, the aim of the second chapter is to give an overview of the work carried out on simulation of flow of cement-based materials using computational fluid dynamics (CFD). This includes governing equations, constitutive equations, analytical and numerical solutions, and examples showing simulations of testing, mixing and castings. The third chapter focuses on the application of Discrete Element Method (DEM) in simulating the flow of fresh concrete. The fourth chapter is an introductory text about numerical errors both in CFD and DEM whereas the fifth and last chapter give some recent examples of numerical simulations developed by various authors in order to simulate the presence of grains or fibers in a non-Newtonian cement matrix. 410 0$aRILEM State-of-the-Art Reports,$x2213-204X ;$v15 606 $aBuilding materials 606 $aStructural materials 606 $aMechanics 606 $aMechanics, Applied 606 $aBuilding Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/T23047 606 $aStructural Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z11000 606 $aTheoretical and Applied Mechanics$3https://scigraph.springernature.com/ontologies/product-market-codes/T15001 615 0$aBuilding materials. 615 0$aStructural materials. 615 0$aMechanics. 615 0$aMechanics, Applied. 615 14$aBuilding Materials. 615 24$aStructural Materials. 615 24$aTheoretical and Applied Mechanics. 676 $a693.852 702 $aRoussel$b Nicolas$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aGram$b Annika$4edt$4http://id.loc.gov/vocabulary/relators/edt 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910299729203321 996 $aSimulation of Fresh Concrete Flow$92165816 997 $aUNINA
