High shear mixing enhances the thixotropy of concrete for digital fabrication
Résumé
Each digitally fabricated concrete layer has to evolve from a fluid suspension during mixing and pumping to a cohesive material after deposition that maintains a strong interface with, and mechanical resistance to, the next deposited layer [1]. Consequently, thixotropy is very important for concrete digital fabrication as it enhances the structuration of the cement paste [2].
