Slump Cones

Determine the workability of your concrete mixture with the slump cone test — and concrete slump cone equipment. Certified Material Testing Products carries a wide range of slump cone equipment, from the slump cone itself to the base and rod sets needed to hold the apparatus in place while the concrete sets. You can count on all of the slump cone equipment being of the highest possible quality to help you achieve accurate, reliable and repeatable results.

Slump cones are essential equipment used in the concrete testing process to determine the workability or consistency of concrete. Workability refers to the ease of placement and compaction of freshly mixed concrete, and it is a crucial factor in determining the strength and durability of hardened concrete. A slump cone test is performed by filling the cone with freshly mixed concrete and compacting it with a standard tamping rod. The cone is then lifted, and the slump, or the difference in height between the top of the cone and the displaced center of the concrete, is measured. This value indicates the workability of the concrete.

Slump cones are made of high-quality steel and are designed to withstand the weight and pressure of freshly mixed concrete. They are typically conical in shape, with a top diameter of 4 inches, a bottom diameter of 8 inches, and a height of 12 inches. The cones are calibrated to ensure accurate and consistent measurements.

Slump cones are commonly used in construction projects to ensure that the concrete being used is of the appropriate workability. This is particularly important for applications where the concrete needs to be poured into tight spaces or around intricate shapes, as the concrete needs to be able to flow and fill the space without segregation or excessive bleeding.

In addition to being used for testing freshly mixed concrete, slump cones can also be used to monitor the consistency of concrete during the pouring and placement process. If the concrete is found to be too stiff or too wet, adjustments can be made to the mixture to achieve the desired workability.

In conclusion, slump cones are a critical tool in the concrete testing process, ensuring that freshly mixed concrete has the appropriate workability for a specific application. The accuracy and consistency of measurements provided by slump cones are vital in achieving the desired strength, durability, and overall quality of hardened concrete.
