River Sand

Also known as Feld spathic 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 applications can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium, and other trace elements/minerals.
