Extrusion Flow Modelling of Concentrated Mineral Suspensions
Abstract This study deals with the stability of the flow of cement-based materials induced by the extrusion forming process. Recently, such process has gained much interest because of its involvement in 3D printing process. The occurrence of the relative filtration of the fluid through the solid part of the material is governed by a competition between the permeability of the granular skeleton and the velocity of the extrusion process. Based on extrusion tests, two types of plastic behavior are proposed to describe the extrusion properties. The extrusion flow are tested under different conditions, such as sand proportion, ram velocity, die diameter, etc. The moisture contents on extrudates are calculated to describe the fluid filtration and the development of solid volume fraction. The experimental results are to be compared with the model prediction of the extrusion tests.
