Measure the mass of the sample taken from the original position! Determine the mass of the sand and water separately, and calculate the density of the sand.
The "Field Density Test" is a test conducted to determine the density of materials such as fill in their natural state, and it is widely performed, particularly for construction types that require compaction management. As information-based construction using TS and GNSS is implemented, there is an increasing number of tests conducted on test fills aimed at determining factors such as the number of compactions, further expanding the scope of its application. Please feel free to consult us when needed. 【Overview】 ■Field: Excavation of test holes, sand injection for testing ■Laboratory: Weighing of residual sand, weighing of excavated soil (moist), weighing of excavated soil (dry) ■Calibration: Measuring the mass of the measuring device, measuring the mass of the measuring device and sand, measuring the mass of the measuring device and water *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Example of Field Density Test (Sand Replacement Method)】 〈Field〉 ■ Excavate a test hole of the required size and collect in-situ samples. ■ Then, pour sand filled in the measuring device into the test hole. 〈Laboratory〉 ■ Measure the mass of the sand remaining in the measuring device and the mass of the sample collected from the in-situ location. 〈Calibration〉 ■ Determine the mass of the sand and water filled in the measuring device, and calculate the density of the sand. ■ This calibration must be performed as it is essential for determining the density of the soil. *For more details, please refer to the PDF document or feel free to contact us.
