As a dense and hard material, dolomite is widely in demand in construction - in finishing works and for the construction of low-rise buildings. Also, the mineral is an important element of the refractory treatment of blast furnaces for steel processing and is used as a flux for melting iron materials. In addition to the above, dolomite:
used as raw material for ceramics, glass, cement, fertilizers;
used in the production of pesticides, paints;
is the basis for creating decorative and building stones;
acts as a filler in the production of asphalt, concrete blocks, etc.
A large amount of powdered dolomite (dolomite flour) is actively used in the creation of float glass. Limestone material is also added to the soil to reduce acidity and "sweeten" the land. This special material plays an important role in a variety of components used to manufacture residential and commercial construction products:
plasters (including waterproof);
mastics;
roofing systems;
construction connections;
marble and polymers;
concrete blocks;
floor coverings - composite vinyl tiles, etc.
Fly ash is used: In the production of lightweight concrete. Low-cement concrete is used in the preparation of road bases. Fly ash is also used in slag-silicate concretes, which are used to repair roads, airfields, bridges, as well as in the construction of acid-resistant floors in chemical plants, livestock farms, and metallurgical facilities. In the production of foam concrete, its introduction into the foam concrete mixture increases the aggregate stability of the mixture between the beginning and end of the cement dough setting, which prevents the movement of components and prevents negative effects on the formation of the structure. Fly ash easily replaces cement in the production of mortars, ready-mixed concrete, and finished products. It is used as an additive to cement without reducing its activity, is used in the preparation of concrete for road construction, and as an additive to clay in the manufacture of tiles and bricks. As a component of dry construction mixes: production of dry masonry mixes consisting of cement, sand, fly ash, ICP, and powdered superplasticizer.
Rice husk ash is used in the production of special high-quality steel with low thermal conductivity and density. ZRSH is added to the heat-insulating mixture to cover the mirror of the metallurgical ladle, which additionally ensures compliance with the temperature regime of continuous casting processes. Ash is used as a filler in polymers and rubbers for the production of car tires, as an adsorbent for heavy metals for wastewater treatment. In the pharmaceutical industry, ash is added to stabilize emulsions, as an agent, thickener and suspending gel in the preparation of semi-solid products, in perfumery, RHA is added as a filler for toothpastes and creams.
Equally important is the use of rice husk ash as a natural source of high performance amorphous silica.
Oil and gas industry:
Accelerating the process and improving the efficiency of well drilling; increasing the life of drilling equipment; drilling fluids and plug cements of low density and high strength.
