These charts were successfully employed in the last decades of the previous century, but with the increased use of chemical admixtures and the development of more flowable

Numerical simulation of fresh concrete flow: insight and

fresh concrete is a very complex material and its simulations i nvolve complex material models and extensive computations. An exact material model of fresh concrete does not exist, and the researchers use diverse approximations to depict concrete flow. In this paper, we identify the main challenges for

THE RHEOLOGY OF FRESH CONCRETE TRID

THE RHEOLOGY OF FRESH CONCRETE. This book provides information on the workability of fresh concrete. The authors discuss the application and extension of established rheological techniques to the measurement of workability in place of `ad hoc' empirical methods. They show that cement pastes behave according to the Bingham model at low shear
