b This report provides a comprehensive view of workability of fresh concrete and a critical review of the tests available to measure workability and rheological performance of fresh concrete e@ Clarissa@ ekoehler@ The main objective of this study is to eval-uate the workability of fresh portland cement concrete while it is still in the mix-ing truck by determining fundamental rhe-ological parameters (plastic viscosity and yield stress) This guide describes a method for selecting proportions for concrete made with hydraulic cement meeting ASTM C/ CM, C/CM, or C/CM with or without Contents Preface vii Acknowledgements viiiThe importance of workabilityStandard tests for workabilityFlow properties of fresh concretePrinciples of Concrete workability is defined as the efort required to manipulate a freshly mixed quantity of concrete with min-imum loss of homogeneity [1]. The VKELLY Test Index is used for measuring Concrete Workability when evaluating mixtures in the Lab.

This property of concrete is The characteristics of fresh concrete which defines workability are consistency, mobility, and compatability. Consistency is a measure of fluidity while mobility is the ability of The Range of Workability Must Fit the Range of Vibration Energy. If this test is being carried out in the field, the sample mixed concrete shall be obtained.
