Slump is a measure of the consistency of a concrete mix, or its ability to flow, and is often used to evaluate how much water has been used in the mix. Concrete with a slump that is low is very stiff, dry, and hard to work with. Concrete with a higher slump is more fluid and workable. Slump values are measured in the number of inches fresh ...
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.
Jul 11, 2024 · The fluidity of the mix is directly proportional to the slump value. A higher slump indicates a more fluid mix, thereby enhancing its workability. Therefore, the slump value serves as a crucial yardstick in assessing: The ease of mixing. Placing. Finishing the concrete. The quality of the hardened concrete.
The slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Due to this fact, it has been widely used for workability tests since 1922. The slump is carried out as per procedures mentioned in ASTM C143 in the United States, IS: 1199 – 1959 in India and EN 12350-2 in Europe.
Sep 20, 2023 · The concrete slump test provides valuable information on the workability of concrete. In simple terms, it measures the consistency of concrete before it sets. A slump cone test is performed using a metal mould shaped like the frustum of a cone. With top and bottom diameters that differ, the cone is filled with concrete immediately in three ...
Jun 8, 2024 · The optimal slump value depends on the mix design and location. For dry samples, it ranges from 25-50 mm, while wet concrete ranges from 150-175 mm. A shear or collapse slump happens when the upper section of the concrete breaks and slides, showing a lack of cohesion in a high workability mix.

Concrete slump refers to the consistency and wetness of concrete. It is measured using a slump test, where a cone-shaped mold is filled with concrete and then removed, allowing the concrete to slump or fall. The distance it falls is measured in inches or millimeters and is known as the slump. A higher slump, such as 6 to 8 inches, indicates a ...
