What's the difference between silica and regular

Sand is a classification of the texture of a sediment. If sand sized sediment grains are mainly silica mineral or high in silica mineral, it can be classified as silica sand. If feldspar (another mineral) is present in sand sized particles it is sand, but it is not silica sand (it is, obviously, feldspar sand).

Effect of fly ash and silica fume on compressive

01-06-2011  The results of this study suggested that quarry dust (QD), silica fume (SF) and kiln ash (KA) combinations can improve the workability of SCC, more than QD, SF and KA individually. KA can also have a positive influence on the mechanical properties at early ages while SF improved bond between aggregate–matrix resulting from the formation of a less porous transition zone in concrete.

Silica fume - Wikipedia

Silica fume, also known as microsilica, is an amorphous polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm. The main field of application is as pozzolanic material for high performance concrete. It is sometimes confused with fumed silica.
