1. What is Concrete Slump? Definition and basic understanding. 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.
Concrete slump is one of a suite of fresh concrete tests that include air content, unit weight, temperature, and the molding of laboratory samples for strength tests as specified in ASTM C94. These tests document the properties of the concrete as it is delivered to the job site.

Dec 11, 2022 · December 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 items required for a slump test: 1. Slump Cone Mold—The mold is 12-in. in height and known as an Abrams cone. 2. Scoop—To place the concrete sample into the mouth of the cone. 3. Steel Tamping Rod—This is a 5/8-in. diameter, smooth-surfaced, 24-in. long rod with hemispherical (rounded) tips. 4. Baseplate—Or some similar non-absorbent surface. 5...
Obtain a sample using ASTM C172 – Standard Practice for Sampling Freshly Mixed Concrete methods.Begin slump test within five minutes of collecting and remixing the sample.Ensure the test base is smooth, non-absorbent, and placed on a level surface.Once the slump test has started, it must be completed within 2 minutes and 30 seconds.Pro Tip: While you can certainly perform the slump test procedure by yourself, it will go a lot smoother with a helper. 1. Secure slump cone to the base plate using the cone tabs or by standing on the foot holds. The cone MUST remain still throughout the test. 2. Using the scoop, fill 1/3 of the cone with the concrete sample. 3. Rod the material 25...
Jan 1, 2016 · Slump. A slump is the name given to a slide when the underlying failure surface is curved rather than planar. The motion of a slump is rotational, so that portions of the slide drop and rise with respect to the adjacent stable slopes. It is more properly referred to as a rotational slide.
