  • What is the use of quartz and what makes it expensive? | Payal Gour .

    Oct 14, 2016 . What makes quarts expensive? Quartz is one of the most useful natural materials. Its usefulness can be linked to its physical and chemical properties. It has a hardness of seven on the Mohs Scale which makes it very durable. It is chemically inert in contact with most substances. It has electrical properties.

  • Effect of ground quartz sand on properties of high-strength concrete .

    Dec 19, 2017 . Effects of many factors, such as ground quartz sand (GQS) replacement of cement, SiO2 content and specific area of GQS, and steam-curing temperature on the mechanical properties of high-strength concrete that was steam-autoclaved, were investigated. The mechanism of GQS replacement of cement.

  • What is Silica Sand? - Select Sands Corp

    Silica is hard and chemically inert and has a high melting point, attributable to the strength of the bonds between the atoms. These are prized qualities in applications like foundries and filtration systems. Industrial sand's strength, silicon dioxide (SiO2) contribution, and non-reactive properties make it an indispensable.
