• The Sand Cone / Replacement Test Set is used to determine the in-situ density of compacted fine-grained soils using the sand replacement method, providing accurate measurements essential for quality control in earthworks and pavement construction.
• The test involves excavating a hole in the compacted soil layer, filling it with calibrated sand from a container, and measuring the volume of sand required to fill the hole, thereby calculating the soil’s density.
• This apparatus is particularly effective for soils with particles smaller than 50 mm and is widely used in geotechnical investigations and construction projects to ensure compliance with compaction specifications.
