Mini Slump Cone, Steel

Mini Slump Cone, Steel – Certified Tool for Accurate Concrete Testing

The Mini Slump Cone, Steel is a precision instrument used for evaluating the workability and flow characteristics of cement paste and fresh concrete in laboratory and quality-control environments. It is commonly used alongside other concrete testing equipment to ensure mix consistency and performance before placement.

Slump Testing

Slump testing is a widely used method in the construction industry to measure the workability of fresh concrete. This test determines the consistency and flowability of concrete, which directly affects placement, compaction, and curing behavior. The principle behind the slump test is that workability is closely related to the yield stress of the concrete—the minimum stress required to initiate flow.

Slump testing is a critical part of on-site quality control and is frequently performed using tools found in the slump testing equipment category.

Mini Slump Cone: Steel, for Slump Testing

The Mini Steel Slump Cone is manufactured from heavy-gauge spun steel with seamless construction and rust-resistant plating for long-term durability. This tool is designed specifically for laboratory applications and controlled testing environments.

The cone is a ½-scale version of the standard slump cone, measuring 6 inches tall with a 2-inch top opening and a 4-inch base. It is ideal for testing cement paste workability, particularly when evaluating mixtures containing slag, fly ash, or other mineral admixtures that influence flow behavior.

This product is part of Certified MTP’s lineup of concrete slump cones used for both field and laboratory testing.

What Is Slump Testing?

Slump testing is a simple and cost-effective method used to determine the consistency of freshly mixed concrete. It is commonly performed on construction sites to verify that the concrete meets project specifications before placement.

Because the test provides immediate feedback, it allows construction professionals to make quick decisions regarding mix adjustments. Slump testing is often conducted in conjunction with other fresh concrete testing tools to ensure overall material quality.

Fresh Concrete Slump Testing Method

The standard slump test involves filling a cone-shaped mold with fresh concrete, lifting the cone vertically, and measuring the amount the concrete subsides. The standard cone used in field testing is 12 inches tall with an 8-inch base diameter.

For accurate results, proper procedure and equipment—such as a certified slump cone and stainless steel tamping rod—must be used to comply with ASTM and AASHTO standards.

Mini Slump Test for Slump Testing

The mini slump test follows the same principles as the standard test but uses significantly less material. A mini slump cone is filled with cement paste or fine concrete, lifted slowly, and the final spread diameter is measured.

This test is particularly useful for:

• Cement pastes
• Self-compacting concretes
• Low yield-stress mixtures

Mini slump testing is widely used in laboratory research and mix design optimization.

Steel Edition Mini Slump Cone Advantages

The Steel Edition Mini Slump Cone offers several advantages for precision testing:

• Durable, rust-resistant steel construction
• Seamless design for consistent results
• Ideal for repeated laboratory use
• Compatible with ASTM-based testing procedures

Using high-quality tools from Certified MTP’s concrete testing tools range improves quality control, reduces material waste, and enhances testing accuracy.

Mini Slump Cone Applications and Limitations

Mini slump testing is widely used in:

• Quality control laboratories
• Research and development facilities
• Mix design validation
• Testing self-compacting concretes

While highly effective for low yield-stress materials, results can be influenced by environmental conditions such as temperature and humidity. For best results, mini slump testing should be combined with other concrete rheology testing methods.

Do It Right with a Mini Slump Cone

For accurate results:

• Perform the test on a flat, level surface
• Lift the cone slowly to avoid inertial effects
• Measure the final spread carefully
• Account for environmental conditions

When conducted correctly, mini slump testing provides valuable insight into concrete flow behavior and helps ensure successful placement and curing.
