ASTM D1556 /D1156M DENSITY SAND Fineness

Product Description

ASTM D1556/D1556M refers to the Standard Test Method for Density and Unit Weight of Soil in Place by the Sand-Cone Method. Therefore, "ASTM D1556/D1556M density sand" is a specialized product designed for use with this particular test method.

Here's a product description for ASTM D1556/D1556M density sand:

ASTM D1556/D1556M Density Sand

This high-quality, specially graded density sand is precisely manufactured to meet the rigorous requirements of ASTM D1556/D1556M (and often AASHTO T 191) for determining the in-place density and unit weight of soils using the sand cone method.

Key Features and Benefits:

 * Precise and Uniform Grading: The sand is carefully sieved to a specific and consistent particle size distribution. This uniformity is crucial for ensuring reliable and repeatable density measurements, as it allows for consistent flow and filling of the test hole. Typically, few particles will pass the No. 200 (75µm) sieve or be retained on the No. 10 (2.00mm) sieve, and the uniformity coefficient (Cu) is often less than 2.0.

 * High Purity and Low Contaminants: Composed primarily of naturally rounded silica quartz, this sand is clean, dry, uncemented, and free from dust, clay, and other impurities. This high purity prevents interference with test results and ensures accurate density calculations.

 * Consistent Bulk Density: The sand exhibits excellent bulk density consistency, with variations typically less than 1% between determinations. This stability is critical for the accuracy of the sand cone test, where the known bulk density of the sand is used to calculate the volume of the excavated soil.

 * Free-Flowing Characteristics: The sand's uniform grain size and cleanliness ensure it flows freely and smoothly from the sand cone apparatus, allowing for accurate and complete filling of the test hole without voids or bridging.

 * Durable and Reusable (with caveats): While designed for accurate testing, the sand is durable. However, it is essential to re-check its gradation and re-determine its bulk density if it becomes contaminated or after significant changes in atmospheric humidity. Reclaiming sand after testing is generally not recommended unless properly cleaned and re-calibrated.

 * Complies with Industry Standards: Guaranteed to meet or exceed the specifications outlined in ASTM D1556/D1556M, ensuring compliance for civil engineering, geotechnical, and construction projects.

Typical Applications:

 * Field Density Testing of Soils: Used with a sand cone apparatus to determine the in-place density and unit weight of compacted earth embankments, road fills, and structural backfills.

 * Quality Control/Assurance: Essential for verifying the compaction of soils during construction to ensure compliance with project specifications.

 * Geotechnical Investigations: Can be used for determining the in-place density of natural soil deposits, aggregates, and soil mixtures, provided the soil characteristics are suitable for the sand cone method.

Note: This sand is specifically intended for use with soils that are relatively cohesive, can maintain stable sides
