The slump-flow test is a different test. It's similar but not the same. Flow table: http://www.concrete.org.uk/fingertips-nuggets.asp?cmd=display&id=560 Slump flow test: http://www.concrete.org.uk/fingertips-document.asp?id=963 |

The '''flow table test''' or '''slump-flow test''' is a method to determine consistency of fresh [[concrete]]. '''Flow table test''' is also used to identify transportable moisture limit of solid bulk cargoes.<ref>{{cite web|url=http://tmltesting.com/w/index.php?title=Flow_Table_Test|title=Flow Table Test - TML Testing Wiki|website=tmltesting.com|access-date=2015-06-11|archive-url=https://web.archive.org/web/20170501222131/http://tmltesting.com/w/index.php?title=Flow_Table_Test|archive-date=2017-05-01|url-status=dead}}</ref> It is used primarily for assessing concrete that is too fluid (workable) to be measured using the [[Concrete slump test|slump test]], because the concrete will not retain its shape when the cone is removed.
==Application
When fresh concrete is delivered to a site by a truck mixer, its consistency needs to be checked before it is poured into [[formwork]].
Line 22 ⟶ 23:
* The cone is lifted, allowing the concrete to flow.
* The flow table is then lifted up 40mm and then dropped 15 times, causing the concrete to flow.
* After this the diameter of flow of the concrete is measured
