Webb16 feb. 2024 · Concrete Slump Test is a measurement of concrete's workability, or fluidity. It's an indirect measurement of concrete consistency or stiffness. A slump test is a method used to determine the consistency … WebbFollowing the adoption of the new European Standard for Concrete in 2003 (BS8500), consistence (workability or slump) is now specified as being of a particular class. There are five classes, labelled S1 to S5, with each class spanning a range of slump values. These area shown in Table 1 below:
