Review of Rheology in Cement-Based Materials and Its Application to 3D Printing Using Concrete

This review briefly summarizes introductory understandings of concrete rheology and applications in which rheology plays an important role. A mixture of cement and water is the rheological material classified as dispersed systems involving chemical reactions, and it has been considered the most challenging research subject in the field of rheology. This review introduces the most crucial chemical admixture for fresh concrete controlling rheological properties (so-called superplasticizer) after summarizing the fundamental knowledge of concrete rheology. In addition, recent research trends on 3D printing using concrete, riddled with rheological challenges, are introduced.

这篇综述简要总结了对混凝土流变学的初步理解以及流变学起重要作用的应用。水泥和水的混合物是一种被归类为涉及化学反应的分散体系的流变材料，它被认为是流变学领域最具挑战性的研究课题。在总结了混凝土流变学的基础知识之后，这篇综述介绍了对控制新拌混凝土流变性能最为关键的化学外加剂（所谓的高效减水剂）。此外，还介绍了在使用混凝土进行3D打印方面近期的研究趋势，其中充满了流变学方面的挑战。
