what are the properties in silica sand

The most common constituent of sand, in inland continental settings and non-tropical coastal settings, is silica (silicon dioxide, or SiO 2), usually in the form of quartz, which, because of its chemical inertness and considerable hardness, is the most common mineral resistant to weathering.. The composition of mineral sand is highly variable, depending on the local rock sources and conditions.
