Sand quartz fractionated: classification
It is called so this sand is not in vain, quartz particles are of different sizes, and the use of fractions of a certain size is found appropriate. An important role is played by the form. For the most part, quartz sand fractionated is divided into two groups - construction and molding, but use much wider. It is made of window glass, bottles and medical, as well as chemical containers, the density of quartz sand makes it suitable for obtaining high-quality filters.
Quartz sand, obtained from the sea, has a rounded shape, as well as riverine, and from the quarry and ravine workings, angular-shaped fractions are obtained.
For those who need to transport this material over a long distance, the specific gravity of quartz sand is of great interest. It corresponds to 2.7 g / cm3, with sufficient looseness, the cubic meter of sand will weigh 1,500 kilograms. However, for the most part, sand quartz is sold in bags, packaged in 25 and 50 kilograms. What is important, in the bags material is filled up fractionated, that is, individual particles have dimensions within a certain permissible value.
Quartz sand: application in construction and not only
Fine quartz sand density is considerable, but how you can use it directly depends not only on the size, but also on the shape of individual fractions. For example, if you want to use quartz sand for sandblasting, the use of material extracted from the sea or river for this purpose is completely ineffective due to its roundness. But for finishing of such sand with medium and large sizes of fractions( from 0.63 to 2 millimeters), it is possible to obtain excellent mixtures, for example, decorative plaster.
The best quality is considered to be sand white quartz, which does not have any impurities. Such material does not require enrichment and additional chemical treatment. White sand is used not only in construction, when, for example, it is necessary to obtain bulk floors of high strength, but also in the landscape design of .Its direct opposite is quartz sand molding, the quality of which leaves much to be desired. For the most part, characterized by fine granularity, the molding material is used for backfilling trenches in construction, as well as for making molds.
Where is dry quartz sand required?
To be used in various areas, both construction and manufacturing, quartz sand must be thoroughly dried. It is during the drying process that the material is cleaned of various impurities, including clay, as well as dust. But, among other things, the above process is necessary for a different purpose. Dry quartz sand is easier to fractionate, after which it is packaged in sacks or big bags, designed for one ton of content.
Dry sand is indispensable for sprinkling paths like garden, without which there will not be any landscapes of the countryside, and sports, along with the park in the city .Also quartz sand, especially colored, is necessary for road marking, in particular for pedestrian crossings and safety islands. They are sprinkled with soft tiles, both from the outside, to improve durability, and from the rear, which is necessary for successful transportation, so that the sheets do not stick together.
