In-Situ Dry Density By Sand Replacement Method

Usually, the soil after compaction in the field has to be checked for the specified dry density. This is usually done by the sand replacement method. This method is also commonly known as the Sand Cone Method. The determination of dry density is of utmost importance as it is required for the estimation of the bearing capacity of the soil.
