Expanded clay small and large - competition or consolidation ?

What concrete block?

Outwardly this material resembles gravel, it is divided into small or large granules, usually oval or ball-like shapes of different sizes, which is why it is often referred to as expanded clay gravel.

These pellets are glassy mass that covers the shell.gravel quality is determined depending on what characteristics it possesses.

granules may be of different sizes from 5 to 40 millimeters.Just depending on the size of the material is divided into three fractions.Well, and the granules which are smaller than 5 millimeters, i.e. 0-5 expanded clay, expanded clay sand considered.

Fractional composition claydite

of expanded clay gravel prepare very spectacular, really observe this process does not work, will prevent a high fever.Fusible clay breeds expanded in an oven at high temperature with constant rotation, and then fired.Obtained mainly large particles, then this crushed expanded clay 20-40 millimeters to give the other factions.

Gravel of this material is characterized by the following properties: it is fire-resistant, cold-resistant, waterproof, has no impurities that can damage the cement.Very often it is used as a filler for the production of lightweight concrete.

Crushed produce crushing particularly large part in the expanded clay fines.Rubble may be the size of 5 to 40 millimeters, but the shape is angular.He, like gravel, used to fill light concrete structure.

«Sand» obtained by roasting the little things out of clay or crushed when a large fraction of expanded clay .The size of the granules after this treatment is less than 5 millimeters.Thus lightweight concrete fill sand and kneaded in its various solutions.

fractions of expanded clay - use

Insulation is considered the main activity object of discussion, but it is not all its application.It possesses sound insulating properties, good properties as an "underlay" material.This means that it can be used for concrete screed, taking as a basis for better or expanded clay 10-20 mm fraction is slightly smaller.

also a material for the manufacture of concrete, resistant to any colds, having a good flame-retardant performance and completely impervious to rot.All these positive features and the ability of the construction of the "miracle" is often used to backfill the foundations of the construction of buildings.More

the material used for the construction of a variety of baths, both modern and traditional Russian, which are built of wood.It is useful and as thermal insulation for the walls of the bath: easily achieved the desired temperature and keeps the required time.And there is no difference, use a small fraction expanded clay or large.

Paving, such as plumbing or heating system, consider the purchase of expanded clay.This allows you to be completely sure that the heat in the pipes will get you, and not the frozen ground.

If the accident happens, you will not have to dig hard ground to detect leakage.And after the repair, you can use the same concrete block again, because it does not lose its properties.

This material is used not only in construction.It can be included in the turnover in the garden area, for example, for the improvement of the track, or even increase yields, just insulate plant roots.In this case, you can use the expanded clay, fraction 10-20 mm will give them drain.The same can be done with plants.Only in this case it is better to take concrete block 5-10 mm.
