Soil mechanics - Wikipedia

Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay, silt, sand, and gravel) but soil may also contain organic solids and other matter.

Relative density is that pure number which denotes the ratio of the mass of a body to the mass of an equal volume of a substance taken as a standard. This standard is usually water (at 4°C) for solids and liquids, and air free or C02 or hydrogen (at 0°C and 1 atmosphere = 1.013 x 105 Pa pressure) for gases.

Damp (structural) - Wikipedia

Structural dampness is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure. A high proportion of damp problems in buildings are caused by ambient climate dependent factors of condensation and rain penetration. Capillary penetration of fluid from the ground up through concrete or masonry is known ...

The moisture column test for Sand B (Figure 3) shows that after 24 hours, the sand has dried to a more ideal moisture of 14% at 7 inches from the bottom of the column and after 48 hours the 6-inch depth is optimal at 15.5%. Sand B can be installed at about 6 inches of sand given its lower moisture retention and better drainage characteristics.
