Description
AZA 0879: Precision for In-Situ Soil Density Determination
The AZA 0879 Sand Pouring Cylinder from Azalab is a fundamental and indispensable tool for civil and geotechnical testing professionals. It’s designed to precisely determine the in-situ density of soils, forming the core of the widely used Sand Replacement Method. This apparatus is vital for quality control in earthwork construction, road building, and foundation preparation. Accurately assessing the dry unit weight of compacted soil directly in the field is crucial for verifying that construction meets specified compaction requirements, which in turn ensures the long-term stability and performance of engineered structures.
The principle of the Field Density Test with this cylinder is effective and straightforward. A small, carefully excavated test hole is made in the compacted soil. The volume of this hole is then precisely determined by filling it with a known quantity of calibrated sand (often referred to as ‘Ottawa sand’ or ‘standard sand’) poured from the sand pouring cylinder. By comparing the weight of the sand required to fill the hole with its known density, the volume of the hole is calculated. Subsequently, the dry unit weight of the excavated soil is determined, providing a direct measure of its current field density.
The AZA 0879 itself is a cylindrical container with a conical funnel at its base. A valve or shutter mechanism at the bottom precisely controls the flow of sand into the test hole. This design ensures a consistent flow rate, minimizing voids and ensuring accurate volume measurement. It’s typically used with a detachable circular tray that features a central hole, which acts as a guide for excavating the test hole and a stable platform for placing the cylinder during the sand pouring process. Various sizes are available (e.g., 3 liters, 4 liters, and 6.5 liters), each suited for specific ranges of hole volumes and soil types.
Constructed from robust, corrosion-resistant materials, the AZA 0879 Sand Pouring Cylinder is built for the demanding conditions of field use. Its durability ensures longevity and consistent performance, even with frequent transportation and handling on construction sites. The simplicity of its operation combined with its precision makes it a highly effective tool for routine soil density checks. This method is internationally recognized and conforms to standards such as ASTM D1556 (Standard Test Method for Density and Unit Weight of Soil in Place by the Sand-Cone Method) and IS 2720 (Part 28) (Methods of test for soils: Determination of dry density of soils in place by sand replacement method). For a more in-depth understanding of soil density principles and compaction, additional resources from academic textbooks or professional bodies like the American Society for Testing and Materials (ASTM) or the Bureau of Indian Standards (BIS) can provide valuable information.
By incorporating the AZA 0879 Sand Pouring Cylinder into your field testing protocols, you equip your team with a reliable and accurate means to ensure proper compaction, which is fundamental to the stability, safety, and long-term performance of all earthwork structures.
