Sand - Wikipedia

Sand is a granular material composed of finely divided rock and mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt.Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.. The composition of sand varies, depending on the ...

The use of coarse material is essential to density, since coarse material contains the smallest amount of voids. Different kinds of sand, gravel, and stone vary greatly in the extent of their voids; and by judiciously mixing coarse and fine materials, the voids may be much reduced, and the weight and density of the concrete increased.
