  • Field Density Test of Soil by Sand Replacement Method

    Sand Replacement Method is also known as Sand Cone Method The apparatus used in this field density test consists of a sand pouring cylinder, with pouring cone at its base There is a shutter between the cylinder and the cone2 天前The primary objective of the sand replacement method is to determine the dry density of soil It is used as a control test to check if the soil has acquired the designated dry density after compaction The determined in situ dry density is necessary for the design of pavement and highway as well as for the estimation of the quantity of the baseInSitu Dry Density By Sand Replacement MethodJune 15, 2021 by Saad Iqbal Sand Cone test is a compaction test to measure density of soil in the field You can obtain insitu density of natural soil The test is suitable for determination of the dry density of compact, fine, and mediumgrained soils Sand Cone test is also referred to as Sand Replacement method in India and PakistanSand Cone test Method for Field Density of Soil
