QZS 700

GENERAL: Silicon sand’s main ingredient is silicon in the form of silicon dioxide (SiO2- silica). This corresponds to a group of minerals that are exclusively made of oxygen and silicon, the two ingredients that are in great abundance in the earth’s crust. Although its chemical formula is quite simple, SiO2  appears with different shapes and crystal structures. The most common form of silica crystal is Quartz, hence the name quartz sand.

Silica sand by THRAKON: QZS 700 is a silica sand that has undergone industrial process, cleaning and drying and is graded in different granulometries. The sand comes from rivers and contains no salts or foreign bodies. It is high in silica (SiO2) that gives the product increased hardness: 6-7 on the Mosh scale. Sand grain has an almost spherical shape that gives the product perfect low properties, and binds it with the connecting materials (cement, lime hydrate).

• The product is used in building and many other works such as cement floors (slabs, pipes etc.), industrial floors, cement screed production, laying and joining ceramic setts, drainage works, potable and non-potable filters, golf courts, athletic constructions, tartan covers, sandpits, horse tracks, gardening, etc
• The method of application, the consumption and selection of the appropriate granulometry (or even the combination of more than one granulometries), varies depending on the case.

• Increased hardness, 6 – 7 on Mosh scale
• Spherical grains that give perfect workability and ideal finish to mortars
• Provides solid density and high bending tolerance
• Provides high friction tolerance
• It is chemically inactive and does not affect the properties of the binder
• Not affected by corrosion or air pollution
• Protects from weather conditions
• Smaller water absorption compared to limestone aggregates
• Undergone cleaning and sieving

Stored indoors in closed bags for an unlimited period. Sun exposure of the packages must be avoided because the plastic bags will be destroyed.
