Sand Equivalent Test Apparatus: Aggregate Water Testing Equipment
Aggregate Testing
Aggregate testing is a must in construction and civil engineering industry as it helps to determine the quality and suitability of fine aggregates and granular soils for various applications. One of the key test used in aggregate testing is sand equivalent test which measures the relative proportion of undesirable clay-like fines in granular soils and fine aggregates. Sand equivalent test set is a complete kit that includes all the necessary components such as graduated cylinder, weighted foot assembly and stock solution to perform the test. The test is widely used in construction of roads, highways and other infrastructure projects where quality of aggregates is critical to the performance and durability of the final product.
What is Sand Equivalent Test?
Evaluating the potential for degradation in aggregates during sand equivalent test is crucial as it affects the durability and performance of materials used in construction applications.
The procedure involves using sand equivalent test set to measure the sand in a sample. The principle is simple: sand settles to the bottom of a container, finer particles stay in water. By measuring the volume of settled sand, sand equivalent value is calculated.
This is a must have tool in aggregate testing, a quick and easy way to check the quality of fine aggregates fine and coarse aggregates. Used in construction industry, sand equivalent test is part of the quality control process for various construction materials.
Sand Equivalent Aggregate
To ensure accurate measurements, additional accessories such as Marsh Funnel and Cup, 1 Liter Measuring are available, alongside Clear Plastic Cylinder for Sand Equivalent Test Set. This transparent allows you to observe the test process and see the sand level.
Stock Solution for Sand Equivalent Test is a pre-mixed solution to calibrate the testing equipment and is available in 8oz and 1gal sizes.
Several accessories are available to aid in the testing. Weighted Foot Assembly applies controlled pressure for compaction during the test, plastic lab funnel for precise pouring of samples. Solid Rubber Stopper and Irrigator Tube for sealing and water flow respectively. Mortar and Pestle for sample preparation, Economy and Motorized Sand Equivalent Shakers for different level of automation for agitation.
With a wide range of equipment and accessories, Sand Equivalent Test Equipment category serves the needs of engineers, technicians and researchers in construction and soil. These products ensure accurate sand equivalent testing so you can make informed decisions when evaluating the quality and suitability of materials for different construction applications Static Cone Soil Penetrometer.

Standards
The sand equivalent test procedure involves mixing a sample of the material with a calcium chloride solution, which is then agitated using a motorized sand equivalent shaker to separate the sand and fines particles. The test is typically performed in accordance with standards such as ASTM D2419 and AASHTO T176, which provide guidelines for determining the sand equivalent value of soils and fine aggregates. The test procedure involves measuring the height of the settled material and the total height of the solution, and then calculating the sand equivalent value. The sand equivalent test set is designed to meet these standards and includes all the necessary components, such as a siphon tube, siphon assembly, and rubber stopper, to perform the test accurately.
Aggregates
Aggregates are part of construction materials and their properties affect the quality and durability of the end product. Properties of aggregates:
-
Bulk Density: Weight of aggregate per unit volume. Bulk density and relative density is important as it affects the amount of aggregate required for a specific application
-
Specific Gravity: Bulk Density of aggregate relative to water. Specific gravity is important to determine the amount and bulk density of aggregate needed for a particular application.
-
Aggregate Crushing Value Apparatus: Resistance of coarse aggregate to crushing under gradually applied compressive load. Important to evaluate the end product durability.
-
Aggregate Impact Value: Resistance of aggregate to impact. Impact value is important to evaluate the end product durability.
-
Los Angeles Abrasion: The measures the resistance of aggregate to abrasion. Los Angeles abrasion value is important to the end product durability.
Interpreting Results
Interpreting the results of the sand equivalent test is critical in the quality and suitability of aggregates and granular soils for various applications. The results provide a measure of the relative cleanliness of the material, with higher values indicating cleaner materials with fewer detrimental fines. The results can be used to evaluate the performance and durability of the material in various applications, such as pavement construction, and to determine the need for additional or treatment. The sand equivalent test is often used in conjunction, such as the durability index test, to provide a comprehensive assessment of the material’s quality and suitability.
