The present methods available for determining these properties of fresh concrete are operator sensitive and thus, the properties for same mix of concrete made under same conditions will vary depending upon the workmanship. Even the IS code suggests different methods for different workability and different placing condition. Thus, more judicious methods for determining the physical properties of fresh concrete are required. This seminar consists of such methods for determining the physical properties of concrete viz. shear stress and viscosity. In addition to this the research carried out by various researchers in the field of rheology of concrete has been studied such as the comparison of various types of rheometers, the use of rheometers and workability boxes, rheological properties of self-compacting concrete, rheological properties of ultra high performance concrete and the various types of rheogarphs has been studied.
