Supply of expanded clay

Expanded clay is widely used in construction. This is due to the qualitative characteristics of the material, which allow it to be used in various construction works. Any home craftsman can easily tell you what expanded clay is. However, such a popular material has its own secrets and peculiarities. These are lightweight ceramic balls with a special porous structure. The raw materials for their production are clay shales and various grades of clays, which are accelerated fired in special furnaces. The result is grains with a caked, very dense shell. Air—filled pores remain inside them - their presence determines the properties of the products.The shape depends on the manufacturing method and can be different. The elements are produced in gradation from an almost regular ball to details similar to a cube. The shape does not affect the characteristics of the product in any way. The sizes also vary. In some cases, a mixture of different fractions is used, which allows, if necessary, to lay the elements as tightly as possible.

Varieties of ceramic material
The main feature by which the classification is carried out is the size of the grains. Based on this, there are three groups::

Expanded clay sand
The size of the granules does not exceed 5 mm. It is made by grinding large fragments of ceramic mass or by firing the remains of clay raw materials. The fine fraction is good as a filler in the manufacture of cement mortars, ultralight concretes, etc.

Expanded clay gravel
It consists of only rounded grains ranging in size from 5 to 40 mm . They are produced by swelling clay blanks in furnaces. They have the highest possible insulation characteristics. It is used as insulation materials for various purposes and in the production of concrete blocks.

Expanded clay crushed stone
These are the largest elements, ranging in size from 5 to 40 mm. Moreover, the difference in size can be significant. Any shape is found, but most often these are angular details. It is made by grinding pieces of ceramic mass. It is most often used as a filler in the manufacture of lightweight concrete.

The material can be purchased with delivery in the form of porous granules – this is the structure. The production of pellets is characterized by low cost and consists in firing low-melting clays. This process is also called heaving. In the end, a material with granules of different fractions is obtained. Unfortunately, there are no expanded clay factories in Sochi, which leads to a high cost in Sochi. Delivery to Sochi, as well as delivery to Krasnaya Polyana of any fractions is carried out for various areas of construction. We sell all fractions – small (expanded clay), large and medium. To save on the purchase, you need to determine the required size of pellets. This way we will be able to offer you the best price.

The delivery in Sochi is carried out by the InertGrad company, the material has the following technical characteristics: it is frost-resistant, has a high degree of strength and density.

All these indicators depend on the grain size. This must be taken into account in order to buy Sochi expanded clay from the InertGrad company with the required values of density, strength and frost resistance.
