ABSTRACT
The importance and use of mineral wool based on blast furnace slag in construction works were discussed
Keywords: ceilings interior surfaces, synthetic resin, noise insulation, heated wall panels
INTRODUCTION
Blast furnace slag forms a practically inexhaustible supply of raw materials for the production of mineral cotton. The ash formed during the combustion of pulverized fuel in TES steam furnaces is used to prepare thermal insulation concretes. Mineral cotton and its products are widely used in various fields of construction. Mineral cotton is used in housing construction for:
— in brick, concrete and wooden houses with wall heating and inter-storey barriers;
— in the heating of the elements of the barrier structures of prefabricated houses manufactured at the factory:
— in the heating of the elements of the barrier structures of prefabricated houses manufactured at the factory.
MAIN PART
Mineral cotton mats with embroidery, synthetic resins and other binders are often used in housing construction. Mineral wool heated wall panels are shown in Figure 1. Figure 2 shows the construction of the lift and light brick walls with mineral wool heating, and Figure 3 shows the 8-9-storey building with the help of a sliding formwork (Sweden). The heating of the house is shown. The mineral wool heater in the barrier structure of the building is as follows:

a) have a thickness that provides thermal resistance to the barrier structures and meets the design requirements;
b) have a thickness that provides thermal resistance to the barrier structures and meets the design requirements; d) should not be subjected to weights other than its own to prevent subsidence and voids in structures.
In industrial construction, mineral wool in the form of slabs is used to heat the roofless roofs of buildings. Mineral wool boards are used in the construction of the barrier of the refrigerator. Slab contraction joints should intersect at the openings for columns and should intersect at the openings for columns..
CONCLUSION
Mineral wool is widely used in thermal insulation of pipelines for hot water, steam, air and gas. Mineral wool is packed into asbestos-cement shells, sheet steel or mesh sheets wrapped in pipes. These sheaths are made in specialized workshops, which allows you to speed up the thermal insulation and simplify installation.
