What Is "Slump" in Concrete?

Slump is a measurement of the structure of freshly mixed concrete to determine its suitability for a particular application. 

What Is Concrete Slump Test Equipment Used For?

To measure the consistency of newly poured concrete before it sets, the worker will perform a concrete slump test. Equipment is used to check the workability and ensure the slump of concrete is flowing at the proper rate. When a slump test of concrete fails, it is an indicator of a batch that's been mixed improperly. A concrete clump test is popular among contractors because it's easy to use the test equipment and it's a simple procedure. In field conditions, the slump test for concrete ensures uniformity for multiple loads. 

What Are The Steps in The Concrete Slump Test Procedure?

There are seven steps involved in concrete clump tests. The tester uses a metal slump cone, which is open at both ends with attached handles. Typically, the slump test apparatus' dimensions are 3.9 inches at the top, 7.9 inches at the bottom and a foot tall. To perform the slump test of concrete, the tester will:

  1. Place the cone on a hard, non-absorbent surface.

  2. Fill the cone with a layer of freshly mixed concrete.

  3. Tamp down the concrete 25 times with a bullet-nosed tamping rod.

  4. Add two more layers, tamping down 25 times between each layer.

  5. Strike off the slump test concrete so it's flush with the top of the mold.

  6. Lift the mold upward vertically.

  7. After the concrete slumps, place the cone next to it. Measure the slump starting from the top of the slump to the top of the cone. 

What Are The Possible Outcomes of Concrete Slump Testing? 

As established in civil engineering, four measured results can occur after testing the slump in concrete. The slump will take one of these shapes:

  • True Slump: A true slump in concrete is the desired outcome. This result means the concrete is holding its shape the way it is supposed to for maximum workability. The optimal measurement for slump in concrete is 4".

  • Shear Slump: In this instance, the top part of the concrete shears off and the remainder shifts sideways.

  • Collapse Slump: The concrete is too wet and total collapse is the result.

  • Zero Slump: Zero slump concrete means a very low water-to-cement ratio, resulting in a dry mix. This type of concrete is primarily used in road construction.

The concrete slump range will indicate the type of work for which the concrete is suitable. For example, in a concrete slump chart, a range of 1" to 4" is required for concrete in beams, reinforced walls and building columns.

Is There Any Other Type of Concrete Slump Testing?

Yes, there are other ways to perform concrete slump testing:

  • Flow Table Test: This is used on fresh concrete that's too liquidy to be measured using a standard slump concrete cone test. The following procedure is used to conduct the test:

    • The tester wets the flow table.

    • The cone is placed in the center of the flow table and filled with a layer of concrete.

    • The tester tamps the concrete 10 times.

    • A second layer is added and tamped 10 times.

    • The cone is lifted so the concrete can flow out.

    • The flow table is lifted and dropped 15 times.

    • The diameter of the flow is measured.

  • Automated Slump Meter: This equipment has sensors and controls that measure and display the slump. There are automated slump meters that can add water to the mix while the concrete truck is driving to its destination.
