Flow Performance of High-Fluidity Concrete
Publication: Journal of Materials in Civil Engineering
Volume 16, Issue 6
Abstract
In this paper a particle assembly model was proposed for high fluidity concrete in the fresh state. This particle assembly is composed of cohesionless particles (aggregates grains) and cohesive particles (cement grains) surrounded by mixing water membranes. By using a microscopic approach and expanding Eyring’s rate process viscosity theory, the flow mechanism of high fluidity concrete having interfriction was clarified, and its flow curve was examined. Furthermore, the effects of normal stress and environmental temperature on the flow behavior of high fluidity concrete were investigated quantitatively. Finally, a shear test apparatus was developed and a series of shear tests were performed to verify the obtained theoretical results.
