Testing fresh concrete - Part 2: Slump test
Also Known As:
The DIN EN 12350-2 standard outlines a method for determining the consistence of fresh concrete using a test called the slump test. This test is designed to measure the deformation of a concrete specimen when it is subjected to a vertical slump. The standard specifies that the slump test is sensitive to changes in the consistence of concrete within the range of 10 mm to 210 mm.
However, the standard cautions that measurements beyond these limits may not be suitable and alternative methods should be considered. Additionally, if the slump continues to change for more than 1 minute after the cone is removed, the slump test is not considered an accurate measure of consistence. It also states that the slump test is not suitable when the maximum size of the coarsest aggregates (Dmax) used in the concrete exceeds 40 mm.
