Mechanism of vibratory action in the fresh and plastic concrete

Petar Krstulović, Sandra Juradin

Abstract

The designed oscillatory rheometer, enabling continuous recording of acceleration data for piston oscillating in the sample, is described. An analytical solution for piston oscillation in the pseudoplastic fluid, approximating behavior of the fresh and plastic concrete, is presented. A material coating, with properties similar to those of a Newtonian fluid, forms around every grain and hence reduces sample resistance to remodeling and compaction. The influence of vibratory action on plastic concrete and similar materials is described.
