Description / Abstract:
Introduction
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.
