Determination of field density using the sand replacement method involves three steps. The first step involves calibration of a sand-pouring cylinder. The soil density is measured in the second step and then the water content and dry density is measured in the third step. The various stages of the sand replacement method are shown in Fig. 9.26.

Core cutter method is used to determine the in-situ density of fine-grained natural or compacted soils free from aggregates using a core cutter. Principle : In this method, a core cutter is driven into the undisturbed soil at the site and the in-situ density is determined by taking the weight and volume of the soil along with the core cutter.
