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 ...
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 ...
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.
The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch. The test is popular due to the simplicity of apparatus used and simple procedure.
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.
Concrete Slump Test Procedure. 1- Firstly, the internal surface of the mold is cleaned carefully. Oil can be applied on the surface. 2- The mold is then placed on a base plate. The base plate should be clean, smooth, horizontal, and non-porous. 3- The mold is filled with fresh concrete in three layers.

Jun 8, 2024 · The concrete slump cone is essential for conducting the concrete slump test, as it helps determine the correct water content and evaluate the flowability of the batch of concrete. Additionally, ensuring that the slump cone meets the required dimensions as per BS EN 12350-2 is crucial for obtaining accurate and consistent results with fresh concrete and hydraulic cement concrete.
