Additive manufacturing of a rheological characterized cement-based composite material

Abstract:

This study aims to determine the correct amount of components to formulate a mixture of Short-Reinforced Fiber Cement Composite (SRFCC) material, characterize its rheological behavior, and evaluate its performance in the additive manufacturing process. Basic concepts from rheology and cement-based materials were used, making emphasis in their applications for manufacturing processes. The experimentation procedures for a SRFCC were described. In addition, the experimental extrusion system is depicted, in which the validity of the material was verified according to its behavior during the 3D printing process. The results derived from the rheological characterization were presented, allowing for the determination of behavioral and intrinsic properties of the material. Lastly, a series of optimal parameters for a successful extrusion process was established.
