Abstract:
Recently there has been rapid development in the field of concrete technology. New cements and new mineral and chemical admixtures affect the fresh concrete workability in a way that is not properly reflected by empirical test methods. Also, new production techniques require more proper specifications of the fresh concrete properties. There is a great need, therefore, to take a more basic approach to the testing and specification of the fresh concrete workability. Recent experiences on the use of a coaxial cylinders viscometer for testing fresh concrete properties are presented.
