2018-10-28  such situations, the sand replacement method is employed to determine the field density. In sand replacement method, a small cylindrical pit is excavated and weight of the soil excavated from the pit is measured. By measuring the weight of sand required to fill the pit and knowing its density, the volume of the pit is calculated.

2020-7-4  In the ratio of 40% sand the cohesion decreases 51% and 24% for Pb(II) and Zn(II) when the concentration of heavy metal increased from 0 to 25 cmol/kg-soil. The results of unconfined compression tests show that there is noticeable reduction up to 52% due to Pb(II) with the concentration of 25 cmol/kg-soil in the ration of 60% kaolinite and 40% sand.

2014-2-22  Once the material has been approved and meets the acceptability limits, then in-situ density can be measured, preferably by nuclear gauge or sand replacement tests where the stone content is low. As placing and compaction of the fill progresses, the in-situ TDD can be checked and non-conforming areas quickly recognised and corrective action taken.
