Slump Board: Base Board for Self-Consolidating Concrete Test Set
36 x 36” J-Board for Self Consolidating Concrete (SCC) Testing - 3/8” WHITE PVC
Structural elements with rebar require Self-Consolidating Concrete (SCC) mix designs to ensure voids and honeycombing free structures. The J-Ring test along with the Slump-Flow test is one way to determine if SCC, defined as the ability of the fresh concrete to flow under its own weight to fill all the spaces in the formwork. How well the fresh concrete flows is critical in determining if a fresh concrete batch is properly mixed for its intended use.
Depending on the method, the modified slump cone is placed either inverted or upright in the middle of the J-Ring and filled with fresh concrete in one lift. The cone is then lifted straight up and the diameter of the circular flow of concrete is measured. Same test is then run without the J-Ring and the difference in the flow diameters is recorded as the passing ability. Additional measurements or visual classification may also be done at the end of the test.

Understanding Concrete Slump Test
Concrete slump test is a crucial process in the construction industry, used to measure the consistency and workability of freshly made fresh concrete. This test is essential for ensuring that the fresh concrete mix has the right consistency for its intended application. The concrete slump test measures the ease with which fresh concrete flows, providing valuable insights into the mix’s workability. By performing this test, contractors can detect potential issues, such as an improperly mixed batch, and make necessary adjustments to the concrete mix. Accurate slump testing helps ensure that the fresh concrete is properly mixed and has the right consistency, which is vital for achieving the desired strength and durability in construction projects.
Base Board Features
The base board is the foundation of the concrete slump test apparatus, designed to provide a stable and level surface for the cone. Made from durable materials like steel or plastic, the base board has a smooth flat surface to ensure accurate measurements during the concrete slump test. Compact and lightweight for easy transport and storage, perfect for on-site concrete testing. Has holes or clamps to secure the cone in place to prevent any movement that can affect the slump measurement. The base board ensures that the concrete slump test can be conducted accurately across different loads of concrete, maintaining consistency in the measurements.
Equipment Needed for Concrete Slump Test
To perform a concrete slump test, several pieces of equipment are essential. The most critical tool is the cone, a specialized device designed to measure the slump of the concrete. Typically made of steel or plastic, the cone has a standardized shape and size to ensure consistent results. Alongside the cone, a tamping rod is used to compact the concrete mixture and measure the amount of slump accurately. Additionally, a slump board is necessary to support the cone and provide a stable, level surface for the test. Together, these tools ensure that the concrete slump test is conducted accurately and efficiently, providing reliable data on the concrete’s workability.
Why Accurate Slump Testing Matters for Fresh Concrete
Accurate concrete slump test is to ensure the concrete mixture is right for its intended use. A high slump value means the concrete is too wet and can result in a weak and porous final product. A low slump value means the concrete is too dry and difficult to pour and vibrate. By doing regular concrete slump test, contractors can ensure uniformity in the concrete mix, identifying issues and adjusting accordingly to achieve the desired strength, durability, and workability. Accurate concrete slump test ensures the concrete mixture is balanced which is critical to meet the standards and ensure the structure’s longevity.
Using the Base Board
To use the base board with cone, place the cone on the base board and secure it using the holes or clamps provided. Fill the cone with freshly mixed concrete, make sure it’s evenly distributed. Use a tamping rod to compact the concrete and remove excess concrete and any air pockets that can affect the test. Once the cone is filled and compacted, lift it up vertically to allow the concrete to settle. Measure the distance it settled, that’s the “slump”. This concrete slump value is an indicator of the workability of the concrete, therefore the ease with which it can be poured and compacted, allowing you to adjust the concrete mixture accordingly to achieve the desired consistency.

Slump Board: Supporting Accurate Test Results
A concrete slump board is a critical component of the concrete slump testing process, providing a stable and level surface for the concrete slump cone to sit on. Typically made of durable materials like steel or plastic, the concrete slump board features a smooth surface to prevent the concrete from sticking and remove excess concrete. The primary function of the concrete slump board is to support the concrete slump cone and ensure it is lifted vertically, which is essential for obtaining accurate test results. By using a concrete slump board, testers can ensure that the concrete slump cone is properly aligned, leading to reliable and consistent measurements. This stability and precision are crucial for maintaining the quality and integrity of the concrete mix, ultimately contributing to the success of construction projects.
