About Sand Pouring Cylinder - BS
Specification:
A sand pouring cylinder isa geotechnical tool for determining soil density in the field, consisting of a pouring cylinder, a calibration container, and a metal tray with a central hole, available in standard sizes like 100mm, 150mm, and 200mm.The pouring cylinder, typically made of cast iron, has a conical funnel and a shutter to control sand flow, while the calibration container is used to determine the bulk density of the testing sand.The dimensions and components can vary slightly between manufacturers, but all aim to provide an economical and reliable method for soil density testing, referencing standards like IS:2720 (Part XXVIII).
-
Pouring Cylinder:
A large cylinder, often made of cast iron, with a conical funnel at the bottom and a shutter.
-
Calibration Container:
A smaller container, typically made of steel, with a specific diameter and depth, used to calibrate the sand.
-
Density Tray:
A metal tray, usually square, with a central hole to align with the test pit and the pouring cylinder.
Standard Sizes (Diameter):
- Small (100mm):Used for testing fine, medium, and some coarse-grained soils.
- Medium (150mm):Suitable for soils with medium to coarse grain particles.
- Large (200mm):Designed for soils containing gravel, stones, and aggregates.
Typical Specifications for each Size (Examples):
-
100mm/115mm Set:
- Pouring Cylinder: 115mm internal diameter.
- Calibrating Container: 100mm internal diameter, 150mm deep.
- Density Tray: 300mm x 300mm, 40mm thick with a 100mm central hole.
-
150mm/152mm Set:
- Pouring Cylinder: 152mm internal diameter.
- Calibrating Container: 150mm internal diameter, 200mm deep.
- Density Tray: 500mm x 500mm, 45mm thick with a 150mm central hole.
- A hole is excavated in the field.
- The pouring cylinder is placed over the hole, and the shutter is opened to allow a specific amount of calibrated sand to flow into the pit.
- The sand fills the excavated hole, and the volume of the hole is measured by the volume of sand used.
- The testing sand's calibrated bulk density is determined using the calibration container.
- Using the volume of the hole and the known bulk density of the sand, the field density of the soil can be calculated.

FAQ's of Sand Pouring Cylinder - BS:
Q: How is the Sand Pouring Cylinder - BS used for soil density determination?
A: The cylinder is placed over a pre-prepared hole on the soil surface. Sand stored in the graduated cylinder is poured to fill the hole and calibrate the displaced volume. This process helps accurately determine the in-situ density of the sand or soil as per the BS 1377: Part 9 standard.
Q: What are the benefits of the brass construction and polished finish?
A: The use of brass and a polished finish ensures the equipment is highly durable, corrosion-resistant, and easy to clean, which makes it reliable for repeated use in various environmental conditions typically encountered during field or laboratory testing.
Q: When is the Sand Pouring Cylinder - BS recommended for use?
A: This apparatus is ideal for use during geotechnical investigations, quality control on construction sites, and whenever precise measurement of soil or sand density is required for compliance with BS 1377: Part 9 specifications.
Q: Where can the Sand Pouring Cylinder - BS be deployed effectively?
A: The instrument can be utilized both in field situations (such as civil engineering construction sites) and laboratory environments, providing accurate density measurements wherever the manual method is permitted by standards.
Q: What accessories are supplied with the Sand Pouring Cylinder - BS?
A: Each unit includes a metal tray, a cylindrical pouring device, and a calibration container, ensuring all necessary components are available for immediate and standard-compliant testing.
Q: How precise are the measurements obtained with this device?
A: The cylinder is calibrated to a high degree of accuracy, offering a resolution of 0.01 L and a measurement error within 0.01 L. This ensures dependable, detailed density results for every test performed.
