Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.

In this research, the marble/granite processing waste (MGPW) was used as mineral addition, to improve the concrete viscosity, and WFES was used as a partial substitute (10%, 20%, 30%, 40%) for natural sand in self-compacting concrete (SCC). Compressive strength was evaluated at 7, 28 and 90 days.

Silica sand, also known as quartz sand, is mainly composed of silica( SiO2), which is the main raw material for making glass.Silica sand has ordinary silica sand, refined silica sand and high purity silica sand. The content of silica in ordinary silica sand is between 90% and 99%, the content of iron oxide is less than 0.02%, the content of silica in refined silica sand is between 99% and 99.5

1. Exposure Data. Silica, or silicon dioxide (SiO 2), is a group IV metal oxide, which naturally occurs in both crystalline and amorphous forms (i.e. polymorphic; NTP, 2005).The various forms of crystalline silica are: α-quartz, β-quartz, α-tridymite, β-tridymite, α-cristobalite, β-cristobalite, keatite, coesite, stishovite, and moganite (NIOSH, 2002).

try. Sand and gravel are produced almost exclusively for road build-ing and concrete construction, depending on particle size and shape, surface texture, and porosity (IARC 1987). Silica sand deposits, commonly quartz or derived from quartz, typically have a silica content of 95%; however, impurities may be present at up to 25%.
