The compressive strength of 100-450 MPa, the average bulk density of 2.6 g/cm3, the average density of 2.68 g/cm3, fire resistance up to 1770 ° C. Composition: 70-80 % quartz , mica , feldspar, talc and other minerals. Texture: massive, schistose , spotty . Structure: grain (typically granoblastic ) aphanic . Some varieties of quartzite material used for the manufacture of low-cost Stonecutter’s products as an ornamental stone , is used as a facing stone.
Ferruginous quartzite ( dzhespilit ) . Used for manufacturing dynasty and as a flux ( in metallurgy ) acid-resistant material , construction (including ornamental ) stone . Implemented in the form of crushed stone in construction, flooring , concrete admixtures .
