The Sand Pouring Cylinder is a field testing apparatus used to determine the in-situ dry density of compacted soils using the sand replacement method. It is one of the most widely used instruments in civil and geotechnical engineering for quality control of earthworks, road subgrades, embankments, and other compacted fills.

The apparatus works by pouring calibrated dry sand of known density into an excavated hole in the ground, allowing engineers to accurately calculate the dry density of the soil layer being tested.

Applications:

• In-situ dry density determination of compacted soil layers
• Quality control of road subgrade, sub-base, and embankment compaction
• Field verification of compaction as per design specifications
• Testing of fine to medium-grained soils in layers up to 50cm thickness
• Dam and foundation construction quality assurance

Available Sizes:

• 100MM – Suitable for thin, fine-grained soil layers
• 150MM – Standard size for general field compaction testing
• 200MM – For coarser soils and thicker compacted layers

Features:

• Precision-machined cylinder and cone assembly for consistent sand flow
• Durable galvanised/mild steel construction for field conditions
• Calibration tray included for determining bulk density of sand
• Fitted with a shutter valve to control sand flow accurately
• Lightweight and portable for easy field use
• Compatible with standard Ottawa/Ennore sand used in density testing

Standards: Conforms to IS: 2720 (Part 28), BS 1377 Part 9, and ASTM D1556 for field density determination by the sand cone method.
