What is this quaint sand?

Such sorted sand is obtained by sieving through special fractional sieves. The meaning of this operation in the sorting by gradation of fractional grain. This is done so that during the various construction works sand is used, which is ideal for a particular case.

For production needs, fractionation is performed in units where large sand mountains are mechanically cowardly on vibrating plants through huge screens. But for household needs, all this is done manually, and sieves are bought, or different metal mesh is used, for example, as for plaster.

Building sand - there is plenty to choose from

There is an extensive list of varieties of sand:

  • Career is a natural material extracted in quarries and processed at special industrial stations where high-quality sorting of sand mass from stones and large fractions is carried out. This natural building material is often used in construction work. The average size of the fractions is 1.5-3 mm.
  • River washed, mined in flowing rivers.
  • Career washed - a material from quarries, subsequently washed with a large volume of water for cleaning from clay.
  • Sand dry fractionated - building material obtained by drying in special containers.
  • Sand is a large washed - river or quarry material, sifted in such a way that there are fractions 2-3 mm in size. It is used in the production of high-quality concrete.
  • Quartz - is obtained by crushing the quartz and further sifting it. It is used as an effective filtering agent for decorative cladding of buildings, structures, etc.
  • Molding is a kind of quartz sand, which is distinguished by a bright white color due to clay impregnations present in it.
  • Glass is a subset of quartz sand containing more than 95% silica.

The use of fractionated sand

Sand is so universal material that the scope of its application is truly enormous. The is used to impart increased strength characteristics to concrete, and is also ideal for large block or masonry. In addition, this building material is widely used in the implementation of decorative and facing works.

The quarry is a variety of this material used for pouring under foundations and roads. Washed career sand is used in plaster, as well as in the manufacture of bricks and concrete. A seeded version - in plastering.

Quartz is usually required in the production of glass and glass products, so even the most microscopic impurities in the material will have a negative impact on the quality of the finished product. Fractional fine sand is used for finishing plaster.

As you can see, the variety of the structure of this natural material is very diverse. Fine sand is useful in all sorts of facing works, and large-fraction sand is indispensable in the manufacture of concrete and the erection of various foundations of buildings.

Sometimes for concrete mixes use not one fraction, and a little, and their proportions are strictly observed, it gives them the given parameters of a fortress, time of seizure and durability.
