Abstract

The workability of fresh concrete should be characterized by its rheological properties to overcome the inadequacies of traditional empirical tests like slump test. Generally the rheological properties of fresh concrete are described by Bingham parameters in terms of two physical quantities, namely yield stress and plastic viscosity. Rheometers are used to measure the two rheological parameters. This paper review the different rheometer used for measuring the rheological properties of fresh concrete and discusses the importance of measuring workability of fresh concrete by material science approach.
