  • What is Workability of Concrete? - Gilson Co.

    The slump test was introduced in 1918 by Duff Abrams, a prolific American civil engineer, and concrete researcher, as part of his work defining the effects of water/cement ratio on concrete strength. The test is performed with the slump cone, originally called the Abrams cone, and provides a qualitative measurement of workability but not a direct indication of water/cement ratio.
