The small size of clay particles means they fit closely together, leaving less room for air, water and nutrients to move—especially when pressure compacts them. The particle shape increases the likelihood of compaction, too. Clay particles are flat, like plates, instead of rounded like grains of sand. Clay becomes compacted for many reasons.
Particle size, also called grain size, means the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be used for other granular materials . 
The natural silica sand is in high demand among glass manufacturers, construction companies, building material suppliers, parks and recreation superintendents and landscapers. Why? Because the sand is durable and hardwearing. Plus, its subangular shape makes it ideal for multiple uses.
Regular sand, also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. For example, typical brown sand used for concrete appliions can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium, and other trace elements/minerals.
