The Myth of Soil Amendments Part II If you have a clay

sand to improve a clay soil texture needs to be addressed. Soil texture Soil texture is determined by particle size, which ranges from microscopic clay flakes to more rounded silt particles to sand grains. While undisturbed sandy soils are well aerated and well drained, they are nutrient poor since sand and silt cannot bind mineral nutrients.

Effects of Aggregate Properties on Concrete Size, Grading

May 02, 2017 · Variation in the size of Aggregates changes the water demand, cement content, micro-cracking (strength) in concrete. It also effects pumpability, and durability of concrete. Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix,

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.

This is due to the fact that if there is a greater silt content then this can seriously effect the structural integrity of the concrete it's used in. For this reason, all sand used should be clean and free from clay, salts and any other impurities. There is a method of testing the silt content of sand called (funnily enough) the "silt test".
