摘要: In this paper, the rheological properties of an extrudable cement-based paste are investigated by means original ram extrusion apparatus (capillary rheometer). The experimental results indicate that a careful measurement die pressure is necessary to obtain realistic viscosity vs shear rate curve, as required in technology. particular, it shown optimal test configuration when made directly inside rheometer die. By applying methodology steady-state conditions, has been observed material here evaluated obeys simple power–law equation, range rates investigated, which suitable for industrial process.
