Slump is the vertical displacement measured after a standard cone filled with concrete is lifted. It reflects the consistency and flow of the mix. 2. Significance of Concrete Slump. Role in construction quality. A critical indicator of water-to-cement ratio, affecting the concrete’s strength and durability once cured. 3.
Dec 11, 2022 · Concrete slump is a measure of the consistency of freshly-made concrete. It is determined by measuring the distance that a cone-shaped mold will sink into the freshly-made concrete when the mold is lifted off. The test is performed by filling a cone-shaped mold with fresh concrete, and then lifting the mold straight up and carefully removing it.

The slump test has been around a long time, but in 1918, concrete pioneer Duff Abrams introduced the method to evaluate the consistency or workability of fresh concrete. He and other researchers found that maintaining the optimum slump value for a concrete mix facilitated the material's placement, consolidation, and finishing.
In short: concrete slump is an important test in determining mix design proportions. Here, the slump value should be noted, but also the concrete’s physical appearance and movement. # Concrete. Concrete slump is a standard test performed on fresh concrete.
