Slump test range based on astm
Webb15 maj 2024 · The flow test is a simple laboratory test. This test works on the principle of a jolting of the standard mass of concrete and measured by the flow of concrete. The flow of concrete indicates the workability of concrete. The flow test is used to measure the workability of high or very high workable concrete, which eventually collapses a slump. Webbcalculated from mini-slump values correlate very well with those measured by viscometer, in the case of fresh paste of pure shear flow. Mini-slump testing is a reliable method that can be utilised for the assessment of workability of cements.
