To determine the field density of soil at a given location by sand replacement methodREFERENCEIS-2720-Part-28-Determination of dry density of soils in place, by the sand replacement methodAPPARATUS1. Sand pouring cylinder 2. Calibrating can3. Metal tray with a central hole4. Dry sand (passing through 600 micron sieve)5. Balance6. Moisture content bins7. Glass plate8. Metal tray9. Scraper toolTHEORY AND APPLICATIONDetermination of field density of cohesion less soil is not possible by core cutter method, because it is not possible to obtain a core sample. In such situation, the sand replacement method is employed to determine the unit weight. In sand replacement method, a small cylindrical pit is excavated and the weight of the soil excavated from the pit is measured. Sand whose density is known is filled into the pit. By measuring the weight of sand required to fill the pit and knowing its density the volume of pit is calculated. Knowing the weight of soil excavated from the pit and the volume of pit, the density of soil is calculated. Therefore, in this experiment there are two stages, namely1. Calibration of sand density2. Measurement of soil density Sand Replacement Method PROCEDURE
