| Abstract: | A mathematical model for rheology in concrete conveying is established considering the gravity of concrete and the friction against the pipe by means of Lagrange scheme. Newton iteration is exploited to solve the model and the results calculated with this model indicate a generally good agreement with the test results of free falling bodies. |
