Slump Block is a concrete block unit that is removed from the mold before it has a chance to completely set. This causes the concrete block to keep a slumped appearance like adobe brick. Both structural an non-structural slump block concrete blocks are available.
Slump block concrete blocks, also known as concrete masonry units (CMUs), come in a variety of shapes and sizes, making them a versatile building material widely used in construction. The most common shape for slump block concrete blocks is the rectangular shape, which is available in various dimensions. Standard concrete blocks typically ...

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 concrete...
Testing for concrete slump is a quick procedure that can be performed on the jobsite using relatively inexpensive, but specialized, equipment. For ready-mix concrete, the procedures for measuring slump are defined by ASTM C143 – Standard Test Method for Slump of Hydraulic-Cement Concrete. The basic items you’ll need to perform the test include a sl...
Knowing what the consistency of your concrete mix is when it arrives on the jobsite allows you to make adjustments to the concrete before placement and prevent potential problems later, after the concrete sets. It also is a way to confirm that the concrete you ordered from the ready-mix supplier is within industry standards specific to its purpose ...
When concrete has a higher-than-specified slump, or is too wet, it becomes weaker and more susceptible to cracking. As a general rule, every additional inch of slump reduces concrete’s compressive strength by about 500 psi. As you increase the amount of water in a mix, you also increase the porosity of the hardened concrete, making it more vulnerab...
For most exterior decorative concrete, a slump ranging from 4 to 5 inches is ideal. You want the mix to be similar in consistency to thick oatmeal, without being watery. Avoid slumps greater than 5 inches because an overly wet mix can reduce overall strength and result in a weak, porous surface.
Water reducers and superplasticizersare great alternatives to increasing the slump of a concrete mix without adding excess water. Not only will these admixtures increase the flow and enhance the workability of a concrete mix, they may also boost the strength because less water is needed, with reductions ranging from 10 to 40 percent, depending on t...
If the slump of the concrete delivered to your jobsite is significantly higher than what the job demands, you should reject the concrete mix or take measures to get it within the desired range. Many specifications permit slump variations of up to 1 inch. If the slump exceeds 1½ inches from what was ordered, the quality of the concrete can be signif...
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.
The meaning of SLUMP is to fall or sink suddenly. How to use slump in a sentence. to fall or sink suddenly; to drop or slide down suddenly : collapse; to assume a drooping posture or carriage : slouch…
There are 3 types of the slump. These are: True slump: In a true slump concrete just subsides shortly and more or less maintain the mould shape. This type of slump is most desirable. Shear slump: If one-half of the cone slides down in an inclined plane, it is called a shear slump.
