In the sand replacement method, why is only sand used? Why ...
The (w)hole idea of the sand replacement method is that we need to know the volume of the hole. We need to know that because we want to determine the insitu density of the soil at that location. We dig a hole, bag the soil for weighing later, and then determine the volume of the hole.
