Fractal approach to the fluidity of a cement mortar

Abstract

The fluidity of a cement mortar is a key factor for 3-D printing technology and cement-based materials. This paper introduces the measurement of the fluidity according China's national standard, and a mathematical model is established to reveal main factors affecting the measure accuracy. The result shows the fluidity reveals mainly the rheological property of the mortar, but it is also affected by other measuring conditions, e.g., the vibration properties of the measuring table.
