This document describes 61 test methods for measuring concrete workability. Many more test methods have been developed for a single project or for a specific application and have been sparsely reported in the literature, if at all. Although many of the devices in this document will likely never be used in the future and have been scarcely used in the past, an examination of tests that have failed and tests that have been supplanted by better tests is instructive in recognizing trends in concrete workability research and in selecting key concepts for the development of a new test method. This document first describes key principles and trends in the measurement of workability and then describes the 61 test methods. Based on the successes and failures of past test methods and the current needs of the concrete industry, requirements for new test methods are developed.
