Flowability can be measured by one of several different methods, including slump and flow cone tests. The normal slump range for flowable fill mixtures is 150 to 250 mm (6 to 10 in). This range of slump corresponds to a flow time of 30 to 60 seconds through a standard flow cone. ipod touch pair bluetooth

"WebSep 3, 2024 · A concrete slump is defined as the difference between the cone’s height and that of the concrete in inches. Low-slump concrete has a higher cement-to-water ratio, making it more difficult to work with but also increasing its strength. The amount of effort it takes to work your concrete will reduce for every inch of the slump you add to the mix. " - Earth flow vs slump
