Marble crumb; all fractions

The marble crumb is widely known filler and is used generally for production of impressive plaster mixes. The value of the marble crumb offered by us consists that it has the excellent cubical form of grain with very narrow fractional group differing by the sizes on only 0,5 mm. The most widespread is the fraction 1,5 – 2,0 mm.

 Marble crumb widely use during construction works of different type, where it is considered to be it the most suitable. It is possible to apply it and in exterior finish of buildings, houses of any type and in the same way in various buildings. For design of a landscape — arrangement of garden paths, flower compositions and beds, and also  a marble crumb is a filler by production of sidewalk and mosaic plates.

This material can be used in the different purposes. For example, white crushed stone serves as topping in ice, and in construction as the most suitable material for filling of a ditch. The processed decorative marble crushed stone meets in production of monuments, construction and as a decor for a landscape and rooms.

The marble crumb (karolit) is made by repeated crushing of specially selected marble crushed stone differing in the high level of a whiteness and hardness. Further processes of drying of raw materials proceed at a temperature up to 300 degrees, clarification of raw materials from various impurity and dust removal of a marble crumb. 

 Advantages of use of a marble crumb (karolita):

·                   Radiation safety. The marble crumb is construction material of 1 category.

·                   Intrinsic safety. The marble crumb and products from it are steady against formation of sparks

·                   Fire safety and fire resistance.  The marble crumb belongs to nonflammable construction materials of the class A1 (DYNES 4102) and to the B1 group on an inflammability of material (State standard specification 30402-96).

·                   Frost resistance. The marble crumb is steady against temperature drops.

·                   Conductivity - the marble crumb safely takes away and grounds a static elekstrichestvo. 

·                   Chemical firmness. The marble crumb is steady against influence of acid and alkaline environments.

·                   High decorative qualities. 

 Therefore karolita (a marble crumb) are preferred to be used during the filling of floors and construction of kindergartens, schools, hospitals and other public institutions for which the increased norms pozharo-, iskro-are shown, to radiation safety.

 (Karolit) scopes of a marble crumb:

·                   Production of dry construction mixes, decorative plasters;

·                   Construction (the marble crumb is an environmentally friendly construction material, it is recommended for application at construction of nurseries, medical, public and premises);

·                   Finishing of buildings;

·                   As a basis for production of construction materials (decorative bricks, ceramic and tiled products, a tile and roofing material, front plates, an artificial stone);

·                   Material for production of decorative plasters ("fur coat", "bark beetle");

·                   As a basis for bulk floors and bulk protections;

·                   Additive in kombikorma (calcium from a marble crumb - is necessary for poultry for improvement of quality of a shell and improvement of digestion)

·                   Fillers of filters for water purification;

·                   Soil for aquariums;

·                   Production of souvenirs, pictures, sculptures and monuments.

 

The chemical composition of a marble crumb (karolit) from the Makarovsky pit:

·                   a carbonate of calcium (SASO3), not less – 98,6%;

·                   oxide of magnesium (MGO), no more – 0,2%;

·                   oxide of silicon (SiO2), no more – 0,1%;

·                   phosphorus (R), no more – 0,014%;

·                   sulfur (S), no more – 0,01%;

·                   the sum of one-and-a-half oxides (AL2O3 + Fe2O3), no more – 0,1%.
