Expanded clay is easy, porous in addition, still, and environmentally friendly material which turns out in the course of roasting of fusible clays. It has rounded oblong shape and happens different fractions.
Thanks to the excellent warm and sound-proof qualities, expanded clay is actively applied as a heater or as filler for light concrete (keramzitobeton and). Walls from such material differ in durability, reliability and durability. As in addition, expanded clay is not subject to influence of weather conditions and rotting, and, respectively, does not lose the properties over time and does not decay.
However if you decided to buy expanded clay as a heater, then here It should be noted one minus - this material easily gathers moisture and badly gives it. Though on the other hand, this its quality is ideally suited for cultivation of ornamental and agricultural plants. As expanded clay, without allowing moisture to evaporate, allows to control and regulate water balance. Therefore, do not forget to buy expanded clay if you want to save the flowers from drying.
Expanded clay is absolutely harmless material. You can buy expanded clay without knowing its process of production, but in brief is a porous light material which comes out as a result of clay roasting. Which is located in a tube drum up to 70 meters long, and in the diameter up to 5. The clay time spent in the furnace about 40-45 minutes. Sometimes, for receiving granules, just there is not enough clay placed in the furnace, is for this purpose applied special additives which improve material indicators at the exit. And the most important that it almost does not influence the price.
Expanded clay in Kiev differs with the size of granules and the price. It changes from 2 to 40 mm. The most popular fraction is 10-20 mm (it is applied in construction), and fraction the 5-10th. (For decoration of a bed or as drainage system). The expanded clay price in Kiev depends on the country of the producer. It is possible to buy expanded clay in Kiev from producers from Odessa and Belarus.
As an alternative zasypny utelitel it is better to use penostesteklo granulated (a foamglass crumb). This material represents the made foam glass which does not absorb moisture at all, very easy and is ecologically safe.

Foamglass consists only of glass cells and therefore does not shrink and does not change the geometrical sizes of building constructions under the influence of the weight of eksplutatsionny loadings eventually. It allows to sokhranenit operational properties of a heat-insulation layer.
Existence of this factor is important as materials which sizes are unstable because of thermal expansion / compression or shrinkage during operation can cause damage of waterproofing and finishing layers, form "cold bridges" because of shrinkage, sagging or compression when cooling.
Foamglass has the coefficient of temperature linear expansion comparable to coefficient of temperature linear expansion of materials of which the classical bearing designs consist: concrete, steel, a laying from a ceramic or silicate brick. This proximity of values guarantees stability of the sizes of the foamglass laid or mounted on a steel or concrete structure.
Stability of physical parameters. Foamglass represents the material consisting from closed hexagonal and spherical, having small there is (less than a micron) of opening in walls, cells. Therefore during operation there is no change of such parameters of blocks from foamglass as heat conductivity, durability, firmness, a form, etc.
The factor of preservation of properties of heat-insulating material is especially important at operation of buildings and constructions in view of inaccessibility of material after completion of works eventually.
Relevance of preservation of initial values of parameters of a heater during operation of the building has in modern construction paramount value as because of the increased requirements imposed to eksplutatsionny qualities of the building and because of architectural complication of designs of the building where costs of capital repairs and replacement of the heater which lost the properties are comparable to costs of construction and construction.
