Description

Fresh concrete can exhibit different rheological behavior when at rest than when flowing. This difference is due to thixotropy, which can have important consequences for formwork pressure, multi-lift casting, slip-form paving, pumping, and segregation resistance. This TechNote defines thixotropy and distinguishes it from other changes in rheological properties; discusses the origins of, test methods for measuring, and factors affecting thixotropy; and concludes with its applications.

Keywords: aggregate segregation; formwork pressure; plastic viscosity; pumpability; rheology; rheometer; static yield stress; thixotropy; yield stress.

TechNotes are a committee document that are narrowly focused, single-topic guides, usually practice oriented, that present a specific direction on a particular issue. ACI committee documents (including TechNotes) are reviewed and approved by ACI's Technical Activities Committee.
